Step 1: Step 1: Stitch in Controller

Place the sweater inside out on the ground, working on the back first. Leave some space so that the cord for the battery pack can be easily accessible from the back pocket.

First, stitch in the controller portion of the kit at a place where it will be accessible.

Step 2: Step 2: Stitch in LED Lights

Stitch in the LED lights with the lights facing outward. You can stitch as often as you want, the more you secure in the lights, the more comfortable and sturdy the garment will be: but if you plan to re-use the kit again later you can stitch them in loosely for easy removal.

Step 3: Step 3: Attach Battery Pack

Attach in the battery pack, and you’re good to glow! You can either sew in a small pocket for the battery, or leave enough cord so that it can fit in your actual pants pocket.

Step 4: Step 4: Colors and Patterns

With the wearable tech kit listed, you can arrange different lighting colors and pacing with the buttons for endless variations on your style. If you're not using a kit with a controller, you can use a board like arduino to program the lights to a color or pattern of your liking.
