• 07 – 11: 36 sc [36]
• 12: Attach long hair.

You will need to cut a number of strands to the same length. If in doubt, make the hair longer and trim it later! Do this by wrapping the yarn around a rectangular shape and cut. Each length needs to be twice the length you want the hair, as you need to hook them through the hair cap:

To attach the yarn to the cap, put the hook through a stitch (as you would for a crochet stitch), fold the yarn in half, and using your hook, pull the yarn through the stitch. Make sure there is a loop so you can now pull the tail ends through and secure it.

Once you are done, style and trim the hair, then sew the cap to the head.
