Ok, I found a lacy baby hat that I would like to
A) Do in the round instead of flat as the pattern is written
B) Make and adult size instead.
I think I can figure out the upsizing part, I'll just need to gauge it out with my chunkier yarn and bigger needles.
The basic lace pattern (flat) is this
Rows 5, 7, 9, and 11: Purl
Row 4: K2, *YO, K3, Sl 1, K2tog, psso, K3, YO, K1; rep from *, ending with K2 instead of K1
Row 6: K2, *K1, YO, K2, Sl 1, K2tog, psso, K2, YO, K2; rep from *, ending with K3 instead of K2
Row 8: K2, *K2, YO, K1, Sl 1, K2tog, psso, K1, YO, K3; rep from *, ending with K4 instead of K3
Row 10: K2, *K3, YO, Sl 1, K2tog, psso, YO, K4; rep from *, ending with K5 instead of K4
Well the odd rows would be easy, you'd just knit instead of purl.
As I see it, there are 10 stitches in the lace pattern (between the *), so if I just eliminated that first K2 (and the last extra K stitch which you do on the ending repeat) which I would guess are the selvedge, and CO a multiple of 10, it would work?
