To make a light, I used common corrugated cardboard, a piece of yellow paper, a small piece of acrylic sheet plastic, tape, glue, etc. For tools, the usual paper cutting implements, i.e., straight edge, box cutter, scissors and so on. I use a table saw to cut the acrylic, but it can be cut by scoring lines deeply on your cut line, and then snapping the plastic. Special tools are made for this, but a utility knife will work....USE CAUTION IF SCORING PLASTIC THIS WAY! The light source for these signs are mini christmas lights, available everywhere. They are low amperage, low watt, low heat lights and come in different sized strings, and colors.
