I am getting back to model building after a long hiatus. I would like to improve my work area/workbench. Seems that many people use a sheet of glass to work on for painting, cutting, etc. What do you use for that glass? I stopped at Home Depot and saw their replacement glass but it seemed very thin and fragile. Also, it has sharp edges and corners. Is that what you use? If not, please share what you do use as well as where you purchased it.
