Make your own electronic sewing kit.
Sewing Circuits is a project by some folks I met in Japan: Leah Buechley Nwanua Elumeze and Sue Hendrix (from University of Colorado), a construction kit and acompanying activities that will allow kids to learn about circuits through sewing.
Each kit contained a patch of fabric, a fabric switch, two LEDs, a needle, conductive thread, and a battery attached to snaps. The girls designed images that incorporated the lights and switch, drew their designs with fabric markers and then sewed the lights and switch to their patches, creating a simple series circuit
