I learned recently that the numbers on the back of the hide show how much square feet it is. I did find the second part of this video helpful though about calculating what % you need to add back in to account for waste.
Hides often do have sqft on the back of them, but there have been several times that I've received a side that either had no stamp or small parts were cut out of the side (and used for samples, I suppose) and one of those parts happened to contain the stamped square footage. I'm glad there was some value you were able to glean from the video. Thank you so much!
@@justanazareneleatherco There is a very old method for measuring the area of an irregular shape by using comparative weights. It can be very accurate and very easy to do, as long as you have a balance/scale of appropropriate size and a large piece of scrap material that is at least as large as the hide. You also need a piece of material that you don't mind scrapping that is large enough to make a template of the hide. Newspaper, wrapping paper, butcher's paper, craft paper, old bed sheet or a tarp -- whatever it is needs to be a single piece... you can't tape several pieces together. The weight of the tape will throw off the measurement. You trace the perimeter of the hide onto the paper/fabric and cut it out. Then you weigh the cut-out material. Then cut out as precisely as possible 1 sq ft of the same material and weigh it. The proportion of their weights is equal to the proportion of their respective areas. Example: The paper template of the hide weighs 64.5 g. One square foot of the same paper weighs 3.1 grams. The hide is 64.5/3.1 = 20.8 sq ft. Make sense? You need a scale that is appropriate for the weights you'll be measuring. Like a bathroom scale wouldn't be good here. This was a very common practice in science and math for determining the area of an irregular shape before we had computers and other devices to measure or estimate the shapes directly.

@@justanazareneleatherco Thanks, that makes sense.

That is awesome! I have never heard of that method before. Thanks for sharing!
