I am cutting my scraps into 6.5 inch squares (for charity quilts), 6x2.5 inch rectangles (for Chinese Coin quilts), 5" squares (Lil Twister quilts) and 2.5 inch squares (pattern in 100 Blocks V.4). I sew mostly charity quilts, and cutting scraps to store helps me know what I have instead of storing the fabric pieces. Besides, it's fun to just sit and cut sometimes.
