I also keep anything 1" or wider. I've been using my left over 100% cotton and wool scraps of fabric and batting as mulch in my perennial beds (don't know as I would use them in a vegetable garden... dyes?) I've been doing this for about 2 years and it works great. I throw everything into a box, then when it's reasonably full I take a pair of snips, like the ones you would use for a rag quilt, just stick them into the pile and snip. Great TV watching activity. This cuts up longer strips. Interesting to see which fabrics fade. Some from my first tries are still color fast. Some seem to fade in weeks.
