It's tatted in Lizbeth size 40, Spring Garden and White. It definitely needed blocking after Round 2 because the doily was ruffling quite a bit. Luckily, Round 3 was a lot easier and didn't pose any problems. Here is the finished doily on a black background:
As I was tatting the doily, I kept wondering if Lizbeth thread was too stiff for the project. This seems to happen mostly with white thread, and I don't notice it too much with the colors. Next time I tat something from this book I might try using DMC Cordonnet Special to see if it makes a difference.
