I toss the thin strips and really small pieces, but if it is 2 or 3 inches, it goes into my scraps. I use it when I paper piece. I did see a video once of a lady shredding fabric to make a picture. She piled them into colors, took a foundation piece of fabric, spread the shreds according to her picture she was making, covered it in black toile, and then stitched over the whole thing to hold it in place. It was a wall hanging. I don't think that technique would work for a quilt.
