I want to make some patio doors made of glass (framed with wood) that slide over each other (i.e. don't slide into the wall). I also want to be able to smash those bad boys! So far I've used a Caulk brush textured with wood on the 4 sides and a window texture for the door faces. Looks a bit poo though, and I am unsure how to make them breakable (is it like windows?).
