I am a jumbler. All scraps go into a reusable shopping bag (the cheap, "fabric" kind). Have tried to sort by color/size...hahahaha. Didn't work for me. I do better with just a bag o' scraps. I make lots and lots of scrap quilts. But then again, I am guilty of buying fabric to use in scrap quilts because I needed/wanted that particular color or pattern. Oh well...until the scraps take over my sewing room, I will continue to save them. (I've even transported a huge bagful to my vacation home so I can make scrap quilts there).
