Step 4The Jig is up!
This project does not use a circuit board, and as anyone who has tried to solder components together without one will know, it's HARD! The tree is even more difficult, as the wires and placement of components is aesthetic - you want the wires to be straight, and the tree to be symmetrical.
To overcome this, I used a jig - print out your design (or hand-draw it), and glue it to a scrap piece of wood, at least 5mm (1/4inch) thick. If you have a smooth wood like pine or MDF, you could just draw directly on it.
Find a drill bit the same size as your LEDs (3mm or 5mm, usually), and drill a shallow hole where each LED should go. Ideally each LED will fit snugly into the holes, without wiggling around.
