Materials Needed: three lengths of yarn per person (about 24 inches long, vary the colors), scissors, and tape.
Directions: Holding the three pieces of yarn together, tie one end into a single knot. Either tape the knot to the edge of a table or hand it to a partner to hold. (You could also try tying it to a hanger and having the partner hold the hanger). Twist the first strand in a clockwise direction. Wind it so it is tight about three-quarters of the way down. Hand the yarn off to the partner or tape it down, making sure it stays twisted tightly. REPEAT this with the other two strands being sure to twist in the same direction. Once the last strand is twisted, stretch all three down together and let go of the ends. Smooth the bracelet down with some tugging. Tie the bracelet on and trim the ends.
When you let go, the yarn starts to untwist, but each strand wraps around the others, keeping them from untwisting completely. Ropes are twisted in this way, both to keep them from unraveling and to increase their strength.
