Hooded sweatshirt. (We got ours from Target).
EL Tape (You can find it at Radioshack, or SparkFun).
Inverter for EL tape/wire. (We got this one from Radioshack).
Two AA batteries for the inverter.
Sew on Velcro. (We found ours at Michael’s)
Thread the same color as your hooded sweatshirt.
Follow the steps listed here in the Make: projects site.
Note: our EL tape wasn’t adhesive, so we used a glue gun to stick the Velcro to it.
