I made the prototype of this hat for St Mungo's Woolly Hat day and having wrestled with the crown decreases for a considerable period of time thought that the pattern might be worth sharing. At some point I intend trying out a larger size for those of us (myself included) who do not fit in the "one size fits all" sizing favoured by high street shops.
St Mungo's Simple Hat
125m/137yd heavy sportweight or light double-knit yarn. I used King Cole Mirage
4mm 40cm circular needle, 4mm double pointed needles, or your favoured method for knitting in the round
24sts/4 inches
To fit medium adult head, c.20 inches
C/O 100sts and join to knit in the round, being careful not to twist the stitches.
Knit for 4 inches in K2 P2 rib (or less if you do not wish to have a turn up in the brim)
Then change to stockingette stitch (knit every stitch) for 5 inches. If you wish to have a slouchier beanie make this section longer, but bear in mind that it will require more yarn.
Crown decreases: (when the stitches become too few for the circular needle transfer stitches to the double pointed needles)
