I loved playing with a spirograph as a kid. This necklace takes little more than string and fabric glue to recreate the look of the sirograph drawings using string art techniques.
Step 1: Make the jig for wrapping string
Trace a circle on cork board or foam.
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.
