If you do plan to sell some, talk with your local bead store owners and work out an agreement. For something this size, expect to get $6 a piece. A good way to come up with a price would be to ask the owner what he/she would sell it for, and cut it in half (50 50). Also use local pictures if you live in a tourist town. Good $$ to fuel your projects!
Oh, and don't kill yourself with the soldering iron.

Using something smooth, gently fold down the tape to seal the sandwich. Chopsticks work great for smoothing down the foil, but I used a radio antenna instead (because that makes way more sense).
Step 5: Secure your Sandwich!
Be mindful not to crush the thing while tightening the clamp, you oaf!
