After seeing Rodarte's light-up heels, I decided to make some for myself. The task seemed simple enough. I was able to make a slipcover for the heel of my shoe with embedded light. I used the LED sequins from Aniomagic, you can find them here. The battery pack is from Switch Craft, the materials below account for this. You can use a different battery holder if you like, both Aniomagic and Lilypad's battery holders work well.
