I was happily tatting Galuh from Elegant Tatting Gems by Jon Yusoff, when I realized that I had too many rings in the center. I wasn't sure why, so I kept on tatting. It wasn't until I finished the third cluster that I realized I had missed a join and created an extra ring.
I wasn't in the mood to retro-tat, so I just started over. This looks so much better!
