Here's the finished version of what I showed you yesterday:
here. The reason mine are so uneven is because I have a hard time judging how much bare thread to leave before the lock join. I always leave too much, so that the split chain side is looser than the regular chain side. I know, I know, practice makes perfect, and I should just do a lot more of these. I will eventually.
Right now, I'm tatting another of these, this time in a single color so that I can just use split rings. The blue and white one is size 20. I don't particularly think this flake looks its best in a large thread-- to me, the airiness of the design calls out for a finer thread-- but I had to make this one big because it's for my Grandma, and her eyes aren't what they used to be. The one I'm making now is in size 80. I've still got about 1 1/3 rounds to go, but here's a size comparison just for grins.
I'm also finishing the pattern, incorporating the suggestions made by my wonderful and patient test-tatter, Trayna.
