Oh, my! This was fun to knit (although I ignored it for a while, when something new took my fancy -- can't remember what, now!).
The pattern calls for knitting each module onto the next one, but then cut the yarn at the end of each, and work in horizontal rows. I followed hints found on Ravelry and just knit the diagonal rows from bottom to top, picking up stitches for the next shell along the side of the shell I had just finished. I had two colourways of Kureyon sock, and mainly just let the colours flow, but did occasionally change things up. I don't think it looks diagonally striped at all, does it?
When her birthday came and went, and our tracking information showed that in a week it had got about 5 miles, we contacted the post office and had moments of panic, thinking something terrible had happened, but it did show up where it was supposed to be the very next day, and only a week later than our cheerful salesman had suggested!
I've been promised pictures of it in use, so do stay tuned for that!
