Adding the braids

The braided ties give this crochet monster hat with braids a fun, handmade finish and add extra personality to the ear flaps.

  1. Cut 12 equal lengths of yarn about 24–30 inches long, using 4 strands of each of the three main colors, for each ear flap.
  2. Fold all 12 strands in half and pull the folded center through the bottom of one ear flap. This creates 24 working strands.
  3. Divide the 24 strands into three equal sections of 8 strands each.
  4. Braid the three sections together tightly to your desired length.
  5. Tie a knot at the end to secure the braid.
  6. Trim the ends evenly for a neat finish.
  7. Repeat these steps for the second ear flap.
