I've been leaving bits of Oliver Twists thread on my shuttle as I've finished each Stumpy motif, and my shuttle was getting a little full! I decided to try "Curds and Whey" from Tatting with Visual Patterns by Mary Konior. As simple as this pattern is, I manage to make mistakes every time I try it.
One advantage to tatting with thread as fine as the Oliver Twists, is that it's very difficult to see my mistakes! ; )
