Forget painting: Earlier this month, I took a beginning glassblowing class at Glen Echo with DSL and I.
It was harder than it looked at the Renaissance Festival. You have to keep moving the glass, and you have to do all sorts of things to make the shape -- without managing to burn yourself on the metal tools or thousand-degree molten glass.
Ultimately, we made vases. Or drinking glasses. Or something that can hold pencils.
It was supposed to be purple, but now I can see that I picked up some streaks of blue from the guy that went before me.
I think it's better looking from the inside. See?
