I tried the PG leather, and while useful for some designs, I have sourced some heavier (4 oz) leather for most things I do. That 4 oz leather is a tad thicker at 0.080, and is much more rigid (if that is a goal for you).
I am not making purses and such, but I use it a lot for earrings and that thickness and rigidity is awesome for that.
Two sources locally for it and even though the overall sizes are different it works out to about the same cost.
Tandy. They have some rather large non-dyed Veg-Tanned leather segments. Have to flip through them for good ones, but once found, you can cull the flappy edges and size for usage. I get about 4 to 5 12x20 sheets from one of these.
I use this for prototypes and things that are not needed to be pristine. Some marks and occasional bug bites, which you have to cut out or mark on the masking if making anything important.
Hobby Lobby. They have sheets of Veg Tanned Tooling leather that is my favorite go to for a final earring design. This stuff is wonderfully pristine and very forgiving to work with. Smaller sized at 8 1/2 x 11 inches, but they always honor their 40% off coupons (don’t go there without one) which makes it comparable priced to Tandy.
Not sure 8.5 x 11 is useful for larger leather crafts, but like I mentioned, you can make a lot of earrings out of that sized leather sheet.
Both need to be masked (both sides is my choice). But I also remove that masking that is painted onto the PG leather and mask it with my masking also, so…
