Step 3Prepare the LEDs
iImage Information

Now we're going to prepare the LEDs so they're sewable. Bend the longer lead in a square fashion, coiling it towards the cap. Coil the shorter lead in a round fashion up towards the cap. Repeat the process on the other LED. The difference in coiling style is so that you can tell the difference between each side of the LED, because it's going to matter which lead is which when we sew them.
If you're using a standard toggle switch, now would be a good time to solder on some leads and coil the ends. If you're using a snap, just move along.
