I started this a few months ago, but I must have been tired or something, because I just couldn't wrap my head around the pattern. It is written a bit unclearly, but once I went back with a clear head, I managed to get it. Mostly. I'm still getting confused by it more often than I'd like, but I'm getting there.
Your Birch is beautiful. I laughed at your comment about the French Fleurette pattern - I made the same scarf in the same color, even, last summer and though I knit a lot of lace I too found that pattern tricky. I think it was row 12 that got me more than once! And then my daughter made it in black, and spent hours outside every time she had to rip back a row! Keep at it - it will be lovely!
