Now that you have half your circuit complete, it’s a good opportunity to test it out before you sew the rest. Use another piece of thread to connect the opposite leg of LED to the other side of the battery pack. If it works you’re good to go! If not, here are a couple things to check:
• Is your LED oriented the right way?
• Is there a short circuit somewhere? It’s easier for the electricity to go through the thread than the LED. If a piece of thread is accidentally crossing both lines of thread the light will not light. Sometimes this happens on the back of the piece and you can’t see it on the front.
