all mentioned already but how about kitty toys . my kitties love the ghost type you just hem around it so no threads to hurt them form a head in the middle put some catnip in and tie off with a ribbon.i also sew a few stiches around head and pull before the ribbon so catnip isn't lost. also stuffed mice etc.... gosh muslin has alot a uses. can even use smaller peices for postcards or cards. how bout candle wicking
