You will want to solder all of your wires to your strip light with 18/2 lamp wire. Solder one cube side of the Flexible LED Strip Lights: Solid Colors at a time. This is a total of four pieces of 4" strip at a time. Because you will need to space each strip evenly along each side, first cut your lamp wire into the appropriate sized lengths. Take your first four 4" sections and solder them together. Don't remove the adhesive backing paper yet. After you have a whole side worth of strip soldered together, consider the lamp wire orientation needed to continue on to the next side along your marked path. Don't forget to consider how you will get around each wooden spacer (the connections around the spacers need a little extra attention). Continue all around your cube. After all of your pieces are soldered together, you can remove the adhesive backing paper and mount the strip light to the inner cube!
