DIAMONDS HAT

This hat pattern is a freebie I picked up in a Rowan shop in England.  It was 
designed to be knit flat and sewn together, but I have modified it for knitting in the round.  It looks very nice in Rowan Magpie or any similar wool yarn, and I have also knit it in softer, slightly finer blends.

Gauge:  approx 5 sts/in over stockinette on size 5 needle

YARN:  1 skein (100 gm) Rowan Magpie
NEEDLES:  Circ and/or DPNs 3-3/4 mm (US size 5) and 4-1/2 mm (US size 7)
GAUGE:  approx 5 sts/in over stockinette

Next row:  (k2tog k8) 11/12 times (99/108 sts)
Next row:  k
Next row:  (k2tog k7) 11/12 times (88/98 sts)
Next row:  k
Continue thus, working 1 st less between each decrease on every alternate row until the row (k2tog k1) 11/12 times has been worked (22/24 sts)
Next row:  k
Next row:  (k2tog) 11/12 times (11/12 sts)
Break yarn, thread through remaining sts, draw up tightly and fasten off securely.
