I finished the first of 4 Pi Topper caps that I will knit with Fixation and then dye, because the nubby texture just cries for color.
I used size 3 needles, but I will try 4s for the next cap, as this one is very dense - not a bad thing, but a smidge more drape and size will be a better thing.
I'll probably do one cap in seed stitch, and perhaps use another 6-row pattern for the third and fourth. Using a 6-row pattern makes this hat super easy, as the increases occur after 3, 6, 12, and 24 rounds.
