This pattern was designed by Judith Connors copyright 2008. I think she did a great job! I don't know if it will be one of my heart exchanges as I don't know what the other three people want yet. Guess I will be forced to keep it if no one wants it!
The buttons are 15mm and the thread is size 20 Flora. It is 3". It is a diagram only with few written instructions, but I had no trouble.
I think I might have to tat it again with HDT when I finish working on my TIAS - or the possibility of one!
