I’m getting better at glass, but honestly it’s still a pain in the ass. Right now I keep cracking the glass when I go to engrave. I’m going to figure it out and the results get better time after time. I ordered some glass coasters I’m going to try next to see if they are easier to work with than the rotary attachment on my engraving machine. I seem to be having problems with the graphic skewing on the cylindrical work area.
