Ya, it is pretty much just brained rawhide.
, we laced it up on a big old 2*12 board frame and at the last brain application we walked all over it and kept wetting it down until it was pretty much soft as fresh off the cow. Then me and my brother jumped on it like a trampoline for like 7 hours and it just got stiffer and stiffer. It would work awesome for sandals or moccasin soles though, Possibly a quiver or something.
we have been walking on it and working it and it has been getting softer.My little brother decided it was his new bed.
I can fold it into fourths pretty easy now.
