This carved goose egg is modeled loosely from a stained glass window I saw in an old cathedral. The two dimensional image of the window did require some changes to get it to wrap around the three dimensional egg. It is cut by hand with a high speed cutting tool. There are 96 separate holes in the shell requiring more than 400 cuts to accomplish. Each span of eggshell that remains is just over 1/16 of an inch wide. I have no way to measure the thickness.
