Materials: Sheet of white shrinky plastic, black permanent marker, black necklace and black eyelets. You can draw anything you like and cut out any shape you like. Just remember you work of art will shrink approximately 9x.
Before shrinking the plastic, punch holes with a regular paper punch, once these have been shrunk, they are the perfect size for eyelets!
