Like you, I didn't like scrappy quilts for a long time. Now they are growing on me and I have recently made a few scrappy quilts that I really like! If you really don't think you would like to make a scrappy quilt, give them away or sell them--just get rid of them so you won't feel guilty about them anymore!! But just in case you want to keep them, my method is first to sort by size. Anything 1/4 yard or more is in my yardage stash on comic boards sorted by color. Far quarter size are together also sorted by color. Then I have a small bin of strips for string quilts. All small scraps of squares and rectangles are in a separate bin, attempted to be sorted by color but usually just jumbled!
