I have a hard time getting my head around the idea of building on a plate of glass. I use pins not just to pin thing "down" but also to press other parts down on other parts and to wedge them together and a thousand other things. Still, I'd like to hear from people who build on glass and how they do different things.

My building surface consists of a sheet of dense particle board (about 1" thick) covered with a sheet of blue foam, which in turn is covered with a sheet of smooth corrugated plastic. It's not ideal what it's what's what was available.

I also can't imagine myself building on one of those magnetic building tables. I'd have to entirely rethink how I do almost every building task.
