This pattern is perfect for using scraps of yarn! The stitches used are E wrap and U wrap. Even though a single strand of # 4 acrylic yarn is used, 2 strands of sport weight yarn could also be used. For a chunkier butterfly on a large gauge loom, 2 strands is also an option. Many beautiful butterflies in a single day could be made. Possible embellishments might be buttons, sequins, beads, or whatever is in your scrap drawer.
