I was asked to go into more detail about the "February Hat" I made. First, the picture.
I started CO 70 stitches, which made seven lace pattern repeats. I started with four ridges of garter stitch, then switched to the gull lace pattern from the sweater. After a total of about five inches, I decreased using a vertical double decrease (sl2tog knitwise, k1, psso) within every other repeat to continue the lace in pattern as far as possible. Specifically...
Round 1: vertical double decrease in the center of every other repeat. It's on an all-knit round so that's easier to do the decreasing.
Round 2: work without decreasing. I did the regular pattern for the repeats where I hadn't decreased and k2tog yo k1 yo k2tog in the other repeats where there were only five stitches to work with.
Round 3: (all knit round) I did another set of vertical double decreases in the center of the five-stitch repeats to make them only three stitches each.
Round 4: I did the regular stitches in the big repeats and a vertical double decrease in the smaller ones to make them just one stitch each.
Round 5+: I started the same procedure in the bigger repeats, eventually getting them down to one stitch each. Then one round of k2tog to get down to half the stitches, then close up the hat.
Let me know if anything doesn't make sense or is incorrect. I hope you find this helpful!
