Okay, so you'll also need some woven conductive cloth, a spool of conductive yarn and the FLORA wearable electronics platform, but the sewing is the hard part. Adafruit's Becky Stern walks us through making an emulator-ready fluffy controller pal.
Aside from making your own superhero costume, I can't think of a better reason to learn how to sew. With all the materials readily available at the Adafruit website, there is absolutely no reason anything electronic not be cuddly as well. I have such plans. Such secret, evil plans.
Plan one, learn how to sew.
