Hi Gee Gee,
Co-incidentally, I am also known to my three grandchildren as G.G. My son, lovingly says it sounds like a French "hooker", but I like it and no offense to all the French ladies out there. It stands for "Gramma and the first letter of my last name. My oldest grandchildren are 15 year old twin boys, so I've been G.G. for a long time now.
Thanks so very much for your input regarding the use of a ping pong table for layering large quilts. My concern now would be the portability of such a table. Would it be too heavy and cumbersome for me to carry out from storage? I gather it would fold in half with legs that would collapse underneath. Some thoughts from anyone out there?..... :P
