I finished my c10 Temari last night, and I think it turned out beautiful. There are 12 roses on it, and each is surrounded by a pentagram in the same color. The green base is cone thread, the marking is a very fine silk thread (that I don't remember the name of), and the roses are 3 shades of Trebizond silk. It was engrossing to stitch, but I still found myself wanting to hurry up and get it done.
Tonight I think I will work on a c8 with just an obi wrapping at each division mark. The one I've been looking at doesn't weave the wraps. I wonder how hard it would be to do that.
