Interesting table. I've never thought about using a glass table as a permanent sewing ironing cutting station. I did use an outdoor glass table as a cutting station for a couple of months when I was visiting at a friend's house. It worked well, and was strong enough for what we were doing. Now, would I set my Big Brother on one in embroidery mode and risk it cracking? I just don't know.
I do use an "L" shaped area, but it is a wood table on one side and an oversized TV tray type folding table on the other side for my iron and an ironing pad. I have a different area to cut on if I am doing serious cutting or squaring up, although I do have a 12 x 18 inch cutting mat next to my sewing machine. It works for me.
