This effect looks awesome. I love the white detail at the end. It looks great. Don't worry about what 'they' say. That highlighting effect works very well and it looks beautiful.
I made a mountain using your technic for my Christmas village. I do not consider myself particularly crafty but your explanation made the project easy. Since it is a winter scene I am not going to paint it, but sprinkle it with artificial snow flakes. It is now in the process of drying and I see that I need to put a few more tissues here and there but other than that it came out great. I did have some issues with the tissue tearing but it actually worked to make it more like little rocks. Thanks you so much for doing this. It is so much more realistic than styrofoam. I love the details that come out.
Very nice. I had a really large area of mountain and ground to form, so I just used chicken wire and covered it with newspaper and papier-mâché. It worked really well, too and was very inexpensive. Thanks for sharing your methods with us.

I am following your instructions ( Realistic mountains ULTRA ) and the mountain colors come out really gray, so how do I get the light color mountains that you show on your video. Thanks
Love all of your videos! I just started working on my new layout a month or so ago. Your videos will come in handy when trying to create mountains and the lake I am looking to add. Thank you so much for sharing your techniques with us all!
I will be uploading some videos to my channel at some point. Most likely when things are a bit more complete. Actually just took a break from working on the mountains using your technique!

I read, several years ago, that a quick and cheap way of getting a rock cliff is to use broken tiles from a drop ceiling in a stack with the broken edges as the cliff. After they are put in place just cover them with hydrocal and paint them. I don't know if it works or not as I haven't tried it but it sounds like it would. If it does it is an idea for a new video, possibly.
Laurel Motley Thank you for commenting! 👍 Yes, I typically add Hydrocal on top of the toilet paper, but more to get at similar absorbsion of the areas around the rock molds. It is absolutly possible to shape the Hydrocal surface to what ever texture or form you need.
Hi watched your video on making mountains was great. Trying to find the aluminum net I live in United States is there another name or any ware on internet I can find it. Thanks for your help.
Hi Chris, The product is typically called metal ”mesh”. However.. This video is many years old and I today only use the laminated foil from Woodland Scenics or Noch. This because the mesh over time drops small pieces of cut metal on the tracks and that the cost difference today between mesh and foil is small.
I have just made a hill with your aluminium mesh & toilet paper method and it has been really successful. I have 2 questions... I saw in a reply above that you use 3 layers to make it hard - do you mean 3 layers of toilet paper and glue, or 3 layers of glue/water only? Also I am not sure if you cover the whole hill with hydrocal once it's dry, or only the part near the rock molds. Thank you for your wonderful videos which are just great for new modellers like me.
Very good job Sir, very , very nice solution. I enjoy this tutorial and have learned very much. Excellent DIY project. Thank for sharing with us. Best Regard
I have just started my layout,your tutorials have helped me loads i have been using aluminum foil to create the mountains as we are on a low budget and have been using copier paper in strips dipped into wallpaper paste,as there is a toilet paper shortage due to the corona virus here in the uk.
Hallo, I have a question: when I use a paint with waterbase paint, the toiletpaper gets weak again. Did I used to litle glue whem I assembly the mountain?
Hi Carl! Yes, it sounds like you used too little glue, or possibly waited too short before you started to paint. If you like, you can add a layer of gypsum on the paper surface before painting. It adds to both appearence and strength.
Hi Martin I have a small 70x200cm N-layout and just created the toilet paper surface of my mountains (sloping from about 30cm height). Now I am wondering if it is necessary to add on the gypsum shapes. Do you think they are essential for a realistic look? Thank you for your advice and keep up the great work!
It looks SO REALISTIC! I’m planning on making a whole wall of faux rock in the near future, so this video REALLY helped me out. Thank you so very much!
I like the white dry-brush effect so much, that when I built an outdoor fish pond out of real, unpainted rocks, I dry-brushed them very lightly, and the result was amazing! Since then, I dry-brush any rock or retaining wall I I’ve ever built. I just seems to make textures pop.
Hello, Thanks for sharing this video. Really amazing. I am trying out this method. So far I have layered the paper on top of the mesh. I am wondering if I can use plaster of paris instead of Hydrocal for the next steps (rocks and layering the hardened paper)? What is the difference between the two?
Great tutorial. I followed it for the coloring of the rocks and it worked out very well! I have created a diorama (2m x 50cm) which combines a mainline in H0 and a narrow gauge (H0e) line which serves a mine. At the mine I created a rockface around the entrance to the mine (with track in it). Diorama is open on the backside to see the interior of the mine too. Setting is is Epoche I (appr. 1910) with KPEV trains. I used styrofoam for the base of the rockface and created the rocks by applying egalisation paste (what you use to fill cracks in interior walls). I sculpted rocks into this with a knife. Then I followed the painting technique as in this video. Super result! Thanks! If you want pictures, let me know your email address.
I've watched many videos of making hills and mountains this is the lightest fastest clean way to make them. I's also very inexpensive to do that's the best part as long as we can get toilet paper *lol* This is the system I have decided to use on my layout. This like most of your other videos is really great I like the simplicity of the systems you use makes modeling much easier with fewer tools and co0mponents.
Hey Martin, trying to use your videos as a guideline for my environment. I habe a question about the whiteglue. I can take anyone, just need to be water soluble (wasserlöslich, dont know the word in english)?
Ah yes, "German" toilette paper would work. Unfortunately, North American TP is way too soft and rips / tears too easily. Perhaps need to use paper towels here in North America.
I had already used this system with an even larger chicken wire... however, I use a mix of wall putty with water, which gives a more rigid result... don't you want to try it?
Thank you for your detail and easy to learn video how to make stone realistically. I would appreciate if you can share where I can buy the molding and the stone material.. thank you
Thanks for this video, I watched one of your previous videos on water effects, you use a lot of toilet paper in your videos...lol. Seriously you get very good effects, thanks again for taking the time to show us.
awesome! as my son and i are taking a break after building the benchwork for our second and much larger layout, i have been looking for alternative forms of creating mountains. ive always thought of using glue for its flexible properties but could not think of a way to apply it. conventional methods would not work in my mind and you have the answer! not only is it much less expensive, but toilet paper will, as you show here, would work far better than paper towels. i watched this video a few times and noticed that a lot of simulated rock detail shows up already as you are gluing it into place. i found it to be just what i have been looking for as an alternative to the usual plaster soaked paper towels or plastercloth! and so much less "messy". great tutorial on each aspect shown as to the creation of mountain scenery for model railroading! d
+honestgbfan Thank you very much for the positive feedback! 👍😊 Yes, the toilet paper works great and is always available and low cost. One need to be rather quick with the glue-water-mix wetted brush on the first layer and not try to brush the same paper twice. If you do it will stick better to your brush than to the aluminum mesh.. It's not a problem, only a matter of handling the brush right. Good luck with your layout!
This is, as you use to say, GREAT STUFF. That you have catalogued the tutorials was really the best thing you could do for your YT-chanel. Now it's easy piecy to find what you are looking fore! So the next step for the "Landscape and scenery"-tutorials would be to have a separate catalogue in German and Spanish?
Hi, I've enjoyed your videos. Can you tell me where you purchased the aluminum mesh? Or a brand? I am in the USA and I can't find it as fine as you have. All the brands here are too heavy. Thanks!
I went looking at Lowe's the other day, Found it in the window screen replacement area. It was near the bottom in rolls. You can feel the difference between regular screen and this aluminum screen. The aluminum screen holds the contours you bend into it. Hope this helps!
Mr. Marklinofsweden, Das tut mir leid, aber mein Deutsch is nicht zu gut. Can you use the toilet paper and PVA over styrofoam or do ya have to have the mesh in place?
another excellent video, I'd like to try this on my own layout when it's ready, (if that's ok?) I may do this first on a part where there's no track etc. Thanks:)
Thank you for the positive comment Gary! :) Please give feedback when you got started if there are some things that need more explanation, or changes. Thing you might find tricky etc.. Good to hear so we can improve the methods together.
I like the video and your philosophy of "not so time consuming is better." A question about the aluminum "net" or "mesh" you use. Is this the same material sold as aluminum replacement window screen? What you demonstrated looked more flexible than that since you cut it with scissors and could crumple it with your hands. The window screen I've looked at here in the USA is stiffer, I think. What exactly did you use?
Hi! Thank you! The aluminum mesh is used in the foot of the roof in order to prevent wasps and other insects from nesting. I hope this helps. Look for it in a DIY hardward store.
Dear Mark I'm from Brazil, I live in the city of Vitória, Capital of the State of Espírito Santo. I've been watching his videos and I've become a huge admirer of his work.

News paper and chicken wire???? Let me try!!
What did you use to hold the rocks?Love the wire screen + t paper.
i love it.its so effective.and reasonbly quick and cheap.brilliant job
I am following your instructions ( Realistic mountains ULTRA ) and the mountain colors come out really gray, so how do I get the light color mountains that you show on your video. Thanks
Hi! Have you dry-brushed with white? This typically brings the light color into the mounatain side

As always, Martin ... a wonderfully instructive video! The mountain rock work is EXCELLENT!!! Well done!
Thank you John! 👍😊
Great tips there, many thanks my friend.
You are very inspirational, in your creative and low budget way of working, leading to excellent results
Hello there. .. I watched a lot of videos but yours is the best idea. Please more videos. Thanks.

I do fountains made out of materials you use. But yours are superb . I still get ideas from your works. Respect❤
I really love your technique. You make it look so easy to do. Thanks for posting this tutorial. I've learned quite a lot. :-)
I just saw your video, and I love the idea , one question though, can you spread hydrocal on top of the toilet paper to add texture to the serface??
Laurel Motley Thank you for commenting! 👍 Yes, I typically add Hydrocal on top of the toilet paper, but more to get at similar absorbsion of the areas around the rock molds. It is absolutly possible to shape the Hydrocal surface to what ever texture or form you need.

I have a winter scene and the dry brush works great for areas with light snow.
Thank you, greatly appreciated.
Easy, and the results are "Wow" (spectacular).
Thank you Chris! Is it your Samoyed? I have a Samoyed dog too! :)

And if you run out of toilet paper in the bathroom, you can wipe your butt on your train layout.
jhitt79 😂😂😂
I don't really know whether that is a compliment or an insult.
love it .that made me laff.he does use alot but its effective
Hello,
Thanks for sharing this video. Really amazing. I am trying out this method. So far I have layered the paper on top of the mesh. I am wondering if I can use plaster of paris instead of Hydrocal for the next steps (rocks and layering the hardened paper)? What is the difference between the two?
Hello Santhosh! Most variants of Gypsum works for the casting including plaster of paris. Hydrocal is basically just Gypsum.. 👍😊

9:20 actually in Switzerland we do have these good looking rocks, on cliffs most of the time.
Thank you so much sir
Excellent video, thank you so much!!
very nice layout you got there .Thumbs up for you .Hope you like mine diesel dave's
Tack för en bra video.
Brukar måla botten och trädelar matt svart med spray i tunneln.
Sätter bara liner ca 10-15cm in från varje öppning, lite fusk 😀
Wow you're a true master, what a great result
I've watched so many videos to get ideas to help me get started. This is by far one of the best and most effective. Thank you
Simply wonderful!!! Thank you from Italy!
Hey Martin, trying to use your videos as a guideline for my environment. I habe a question about the whiteglue. I can take anyone, just need to be water soluble (wasserlöslich, dont know the word in english)?
No, I think I should restart my project, but I learned a lot from your videos.
You are like Bob Ross, but in 3D version
Easy and realistic. Plus light weight. Thanks.
Ah yes, "German" toilette paper would work. Unfortunately, North American TP is way too soft and rips / tears too easily. Perhaps need to use paper towels here in North America.

Can you make a video on how to make a mountain/tunnel, please?
Hi! This is a good idea! I´ll add it to the list of videos to make.
incredible. I cant wait to try this technique

+Magnus Hellström Thank you very much Magnus! :) Exactly! ISpanish and German is coming as soon as I find the time.
Thanks.
European toilet paper is like American paper towels, not the soft stuff that is almost like Kleenex. Use paper towels to get the same effects.
Great inspirational video, now i know how to attempt to make mountains on my Z scale track.. thank you
White could be some bird droppings over the thousands of years, too.

Definitely a great video... Very interesting and useful..
Great method and great results. Thanks for sharing
Wie immer perfekt erklärt und tolles Ergebnis. Gruß Toni
Mr. Marklinofsweden, Das tut mir leid, aber mein Deutsch is nicht zu gut. Can you use the toilet paper and PVA over styrofoam or do ya have to have the mesh in place?

is there anything you can use as a substitute for rock molds? ;-;
I am a french Maerklin fan and enjoy a lot your nice videos and tutorials kind greetings from France
+Jakraffin Thank you Jakraffin! :) It´s great to have positive feedback! More videos are in production.
would this technique be suitable for a portable layout that has to cope with some abuse?
With all the toilet paper you use, you must have been hit hard by the pandemic.
Can you please advise? Is HydraCal the same as Plaster of Perris?
perfect, such a great tutorial thankyou for sharing my mind is buzzing with ideas for my country to coast theme.
+Master Dan Great to hear you like the video! 👍😊 Sounds like a great idea for a theme! 👍
Very helpful. Thank you!
uau o seu trabalho e magnífico eu curto muito
Traducción en español...gracias por el paso a paso
Am like you, I don’t like time consuming things so I’ve subscribe to your channel. BTW nice video.
Looks fantastic. Thank you!
hi marklin do you cover all the surface with hydrocal
Sorry for the question: what type of glue are you using?
Congratulations! I learnt much with tutorial.
This tutorial is amazing, wish me luck!
Please let me have an idea how you made the black wall under the rail line
Thank you! I was hopeless before finding your tutorials! :-D
Fantastic going to this on my model railway
Love it sir.thank you for sharing.It's very usefull for my christmas village that I'm building
Dear Mark I'm from Brazil, I live in the city of Vitória, Capital of the State of Espírito Santo. I've been watching his videos and I've become a huge admirer of his work. Congratulations and I have been trying to learn how to make mountains with your techniques, I hope I can do it, maybe not perfectly but we will work hard to see a good result. A big hug from Brazil.
what is the name of powder that you use
You start with a molehill and build up from there
Do you think window screens do the same effect?
Thank you Marklin for all your videos. Probably you'll be astonished to know that I am using your precious guidelines to improve the beauty of my Christmas Crib. I am also thinking about to use all this infos to represent the different scenes of the Life of Our Lord Jesus Christ. Did you suspect that all your good work for us beginners could go so far? Thank you again for your passion and attention to others. Greetings from an italian living in Switzerland. God bless.
Mark you can use foil and shape it to your rock moulds
