this is probably a really dumb question, but do you use the row covers to prevent weeds? what exactly are they for? I really like the idea and will start saving them.
I save all the little snippets and scraps in a container and when it gets full I put them in an old pillow case. I tie the pillowcase closed with a hair tie. Makes a great cat/dog bed. I use the hair tie so I can keep adding to it.
