Step 1: Make the jig for wrapping string
Mark dots at equal points around the circle.
Shove toothpicks, bamboo skewers, or little nails into the dots.
If you're using toothpicks or bamboo, it would help to coat them with a little melted beeswax; brush it on with a paintbrush, then re-melt it with a hair dryer to smooth it out.
Step 2: Wrap the string
Choose the number of pegs to skip for your first necklace link. For this one, I skipped four pegs and wrapped the string over the fifth peg.
Keep skipping pegs and wrapping the string in a pattern you like.
When finished, secure the other end of the string by wrapping it around a peg or taping it to the board.
