Half Persian 3-1

Step 1. Begin with 2 closed rings. The second ring behind the first.

Step 2. Add a ring, pink, that goes through the intersection of the first 2 rings, as shown and place a closed ring, blue, on it.

Step 3. Now flip the pink ring down and make sure that the blue ring is behind the ring before it.

Step 4. Pass another ring through the intersection of the last 2 rings as shown. Add another ring, like you did before.

Step 5. Flip the pink ring down and make sure the blue ring is behind the ring before it. Repeat steps 4 and 5 until you have the desired length. Once you get the hang of this weave it goes very quickly.
