Pattern: Mine with help from the über-clever Elizabeth Zimmerman (July's Pi Shawl from Knitter's Almanac -- if you don't have it go get it, now!) and the indefatigable Barbara Walker (Miniature Leaf II from A Treasury of Knitting Patterns -- another indispensable book for knitters) [Ravelry link]
Yarn: Bliss in Periwinkle from Blue Moon Fiber Arts (sadly discontinued), a sport-weight blend of 70% angora and 30% wool; 100 yards, and I used pretty much all of it
Needles: US6 DPNs and US10 DPNs and 24" circular (I'm a loose knitter, so you might need to go up to a US10 1/2 or US11, if you knit tightly)
Isn't it pretty? It's like a cloud. In fact I'm considering sewing a little comb into it to keep it in place when it's windy. I've been wearing it on the crown of my head, like all the hip, young girls here in NYC, rather than down on my forehead like a beret. Or I might weave some elastic into the headband.
This is a beret from the top down, starting with an i-cord "tail" and increasing based upon π (Pi) as explained by Elizabeth Zimmermann in July of Knitter's Almanac. With this fuzzy yarn I wanted a lacy pattern (a solid hat in angora would be a little oven!). This is how I made mine:
With smaller needles CO 3 stitches. Work i-cord for 1".
Round 1: Kfb 3x as for i-cord (6 st.).
Rd 2: Knitting onto three larger DPNs, [kfb, k1] 3x (9 st.). Join to work in the round.
Rd 3: Knit all stitches.
Rd 4: [K1, yo] 9x (18 st.).
Rds 5-7: Knit all stitches.
Rd 8: [K1, yo] 18x (36 st.).
Rds 9-12: Work Miniature Leaf pattern 1x. (See table below.)
Rds 13-14: Knit all stitches.
Rd 15: [K1, yo] 36x (72 st.)
Rds 16-28: Work Miniature Leaf pattern 3x.
Rd 29: Knit all stitches.
Rd 30: [K1 yo] 72x (144 st.)
Rds 31-38: Work Miniature Leaf pattern 2x.
Rd 39: Knit all stitches.
Rd 40: K2tog around.
Rds 41-end: K1P1 around until ribbing measures 1". Bind off in rib. Weave in ends. Block firmly to open up lacework.
In the round, knit rows 1 and 3.
