I don't save scraps per se but they are always laying around or on the floor. I use them to test sewing or serger stitches. Also for machine appliqué in the hoop or sewn. I think about saving selvedges but I have several jobs and my sewing room already looks like a bomb went off in there so I doubt I'd do much with them. Sometimes you have to let go. I recycle whenever I can and commend all you super savers.
