I finished what I started yesterday, Spring Doily 2 by Vinnie.
Yarnplayer. In size 80, it's really a coaster rather than doily. It measures about 2 3/8 inches (6cm) across, which is just about what I was hoping for.
Overall, I found the pattern pretty easy to follow. I really like how Vinnie has you use a paper clip or marker thread to make a "down" picot so that the whole thing can be done in one pass. It reminds me of some of Iris Niebach's patterns. I knew that the paper clip would create a picot of a certain size, so I tried to make the other picots that size as well. Sometimes it worked and sometimes it didn't.
I'm going to make another one in a more subtly-colored thread and add some decorative picots just to see how different it looks.
