pretty awesome as a wallet, too!
wash a couple of yards to have on hand. wash with hot water and lay flat to dry. dont be afraid to iron with lots of steam. i was short one small piece that needed to look worn, and just steamed the heck out of it and then man-handled it a bit.
don't wash before if you plan to write or print on it. it gets quite bumpy once washed.
once you sew with it, the holes are permanent. if you need to seam rip and sew again in the same spot, just take it slow and make sure the needle goes down in the original hole.
