Primary differences between the "Slash & Spread" and "Mathematical" methods can be expressed in terms of their results. In Sara's example of the "Slash & Spread" process, she ONLY affects the height of the bag. Her modification is applied to only one dimension of the project. Depth and width remain unchanged. However, if the "Mathematical" approach is used, printing the pattern at 120% scale will result in a bag that is taller AND WIDER AND DEEPER. Both approaches to pattern modification are valuable tools to understand, but the clearly have different applications. Which approach you choose to use will depend upon what you are trying to accomplish!! If you only want to change one dimension (for example, "taller") then go with "Slash & Spread". If the desired result is changing all dimensions ("bigger"), then go with printing and a scaled value. Both methods work but they work in different ways. Both have their applications and it is good to understand both.
Thank you Steve !! You are correct ! I am a Mathie . I told my children , you will always need math even if you are a cook , 6 servings recipe , but you need to feed 15 … well kids , how do you adjust the recipe ?
so confuse. i need help if the pattern bag is 10.5 w * 7.5 h * 3 deep but i want it to be as small as 7.25 w * 5 h * 1.5 deep. How much do i decrease it on my printer? Thank you so much with any help. 😅
If you only want to edit the width of a pattern do you have to multiply out both the width and the height or can you just edit a pattern based on changing the width and using the original measurements for height??

As always, you do great work Sara. Very comprehensive discussion. Thanks for taking your time to help us.
Thank you for your tutorials! I look forward to August when your videos start again.
Great video, thank you Sara!!
Thank you, Sara! This is super helpful!
Lots of great information, thanks.
Fascinating show! 👍
Can’t stop staring and that beautiful sleeve 😍
Fantastic info
I'm trying to resize a bag that basically has built in gussets and I'm soooo confused! Hopefully watching this video will help. Thank you!
This is great, thank you so much for this x
I made a custom bag for both of my boys for D&D also.
Really helpful! Thank you!

Hi Sara, how timely is this, thank you.

Am I missing the link to Christina’s channel?
If I like a particular bag online, I take all the info I can get, and draft my own pattern and make it any size I want.
Is there a spreadsheet?
Hi MaryJo, you can see my blog post for a couple of graphics: sewsweetness.com/2022/06/how-to-increase-or-decrease-a-sewing-pattern.html
I noticed that the 90% decrease measurements (for the exterior top)is actually bigger than the original.
Shouldn't it be smaller? 🤔
