Silk does not hold up well to abrasion, which would be a problem for a footstool. It might be okay if it's a heavy silk and the footstool doesn't get much use, but for durability an upholstery-weight fabric would be better. There are lots of choices -- cotton, wool, tapestry, chenille -- just go to a fabric store and ask for advice. Take a picture of the stool with you.

Thank you was afraid it willn't hold up. I believe things should be used, I like alot of men know nothing of fabric.

Come on....no picture of it with its Pucci dress? Awwwwwww! :P
