Saw this in August, I love the idea - there are no small pieces when you can do things like this:

If this link pasted into your browser doesn't work, search for a tutorial titled "Fabric from the Garbage Can". I've been keeping a small trash can ever since I saw it. I don't keep selvage fabric though, but will start now to give for pet beds.
I figure even if I throw it out, I'm still responsible for it. I put emissions into the air to acquire it, used electricity (more emissions) for prewashing, ironing and making something with it, and all the little pieces will break down some day but not until the plastic trash bag I threw them into breaks down. I can't wait to see what I can create with a trash can full o' scraps.
