Electronics. Part I.

Now: ELECTRONICS. I want my LilyTwinkle board and the three LEDs to be hidden inside the pizza, but I want to be able to access the on/off switch and the battery, so I’m going to sew the battery holder onto the back of the pizza first.

Thread your needle with a 12-16” piece of thread (doubled as in the photo, with a double knot at the end to prevent it from pulling through the felt).

Place the battery holder in the upper left corner of what will be the very back of your pizza, with the switch right side up and the positive sides on the left. Sew the upper positive terminal down (I loop each stitch through the terminals three times to ensure strong contact with the conductive thread), run stitches down to the lower positive terminal, and sew that down also. Don't cut the thread yet! We'll continue this circuit on the inside.
