I made a tutorial on how to light up etches but not how to do the actual etching itself. I will have a few tie ins on how to light it up but if you want more info on how to light it up check out my other tutorial.
Step 1: Design
get a design I used the thundercats logo. then blew it up by drawing it myself!! then taped it to the piece of plexi glass. then I hand etched it using an cordless dremel tool. when etching alway try to go down and left this will get a cleaner and deeper cut. notice in the picture the logo in backwards?! this is because I want the cut into half on the back so when flipped around the logo is the right way.
