One of my biggest problems with something vertical, or 3d, is impatience! In fact, I have been known to try to rush things along, not let the pieces dry long enough before turning the work, mess everything up and get really frustrated....like a million times. So today I solved that problem to some degree. I just worked on two pieces at once.
The larger pot
One pot ready to grout, splotchy with thinset and another sealed and drying.
The pot to the right is now about 1/3 done with blue, lavender and blue, and white and blue tessera, as I alternated between that and the bigger green, black and white pot...much less frustrating to wait out the drying time that way. I worked out on my deck much of the day, in spite of the wasp that began hovering around and around under the table, until a little after two. It was 92 degrees and definitely time to come in. Of course my child hurried through her math this afternoon and ran outside to ride her bike.
