When I have an interesting piece of scrap that is on the thick side, I turn it into small boxes, pouches, and the like. For example, I had a piece of chrome-tan white leather. I made a simple cup-type shape about the diameter of an old film case, lined with pigskin, and now it holds my toothbrush up instead of leaving it lying somewhere.
I make random shapes and sizes, then always finds uses for them. One that was about the size of a stack of 3x5 cards became a very handy external hard drive carrying case.
Because these scraps are usually different colors than the hides I buy, i can "pack" my satchel/briefcase quickly by grabbing the things I know I'll need. I have a little first aid kit, one for carrying essential toiletries to the gym, one for holding my leather sewing needles, heck even one just for holding rivets. Ooh that reminds me, I just got a snap setter and need something to put snaps in. No more peanut butter jars for me!
