It all depends on what we call scraps. There are the pieces that are trimmed off to square up yardage--that goes in the wastebasket. Then there are the short ends of binding strips, etc. Those get folded and put with the yardage that is left over. Sometimes I need just a short piece to put into another project and I recognize it better with that "larger" piece. If it falls out, not picked up and has become a dust bunny collector, it goes in the wastebasket, too!
