My current personal challenge for the 25 Motif Challenge was to count only motifs worked from books. I have a bad tendency to get tatting books and never actually work any of their patterns despite my best intentions, so I was trying to work on that. I'm not doing a very good job. I've lost count of when I started, and how many I have done, but I suspect the number is embarrassingly low. I'll go back and count later.
Anyway, periodically, I pick myself back up and try again. Jon generously gave me a copy of her book, Elegant Tatting Gems, and I have been admiring the motifs on other blogs. Here is "Cintamani" which I admired for its curves and being worked all in one pass. I used a size 80 thread by Anchor, which is a gentle mixture of blue and white. I recommend the book, with many 6 sided motifs. Each pattern has both written instructions and a diagram. Depending on your thread choice, they can be snowflakes or small doilies. Mine is just over 2 inches across at the widest point.
