Use old unwanted christmas lights and thrown out cardboard to make a cheap wanna-be LED board.
Step 1: Get Lit
Step 2: Design and Poke
For the poking out holes part I used a screw driver,but a few alternatives are using a pencil, simple pen, drill, large nail, airsoft gun (with pellets), knuckle duster, exacto knife, or and a drill press.
Step 3: Insert There
Take each light and using *Common Sense insert each light into the designed pattern of individual holes.
**Unique Sense and Less Common Sense may also be used.
