Keep those marks!

I wish someone had told me a few tips when I was learning stained glass. One of the tips that I learned later on was using chapstick or beeswax.
When marking your pattern on glass, use a permanent marker. Then cover those lines with chapstick or beeswax to keep them from disappearing when you are using a grinder.
This really saves re-marking the pattern, which is what my daughter and I did over and over. Sure glad someone finally told me about this handy trick.
