DIY LED Plexiglass Heart

Step 3 Etch Your design

This takes some practice as to how deep you should put the tip of the bit, and how fast you should have your Dremel on, but it's easy to learn. I found that going at least halfway down into a 1/8 inch thick piece of Plexiglas gives the best result. Unless you are an artist, you will want to put a template on the bottom of the Plexiglas to use as a guide.
