I have to admit, I’m having a blast with my big box of $0.16 each ceramic tiles from Lowes and a pack of Sharpie oil paint markers! If you haven’t tried it yet, I’d highly suggest it. It’s a whole lotta fun for not a lot of money!!!
I used a couple of my “graph paper doodles”, did a bitmap trace in Inkscape to make the grid lines go away, then let Glowforge do its thing! It’s easy to forget how unforgiving a laser is…every little imperfection (in this case my inability to draw a straight freehand line) becomes part of the design!
