How to Make the 'Butterfly' to hold the Warp Yarn
Start out with the Yarn around one hand, like this.
Begin to Wrap about the hand.
A 'wrap' is each time you turn
around the hand one full cycle.
Keep the opening large, and the wrap loops from tangling with each other.
Now hold the wraps together and wrap about the center.
It looks like a 'butterfly' with a wing to each side.
