Step 4: Test Your Circuit
Insert the coin cell battery into the battery holder with the positive (labeled) side facing up. Turn on the switch and see if your LED row shines brightly! If any of the LEDs aren't illuminating, check your stitches to make sure they are tight. If not you can go in and sew with a bit of conductive thread over the connection point, holding the piece down tighter and making sure that your thread is touching both the board and the original sewn line.
