Also our SPCA takes pillows; hang an old pillow case near your machine & any 100% cotton fabric tidbits can go into the pillow. When it's ½ full fold down the top & stitch it closed, this is the size that fits into the cat cages, maybe your area might want different sizes. Do NOT put batting or threads in the cases. Just another way to recycle those little tidbits that are so hard to throw away.
