Wow, I'm so impressed! And you've only been engraving since 2001?! That's fabulous, and inspiring. I love the dandelions, the fine details of the seeds. Your ferns are terrific, too, so lifelike. And you do it with drills...when I've tried (very amateurishly) using a Dremel I end up getting minute chips along the edges of cuts; do you avoid that, and how? I've thought of trying to use water to cool the glass, but don't know if that makes a difference. Maybe my Dremel doesn't work at high enough speed; what rpms do your tools run at?
