Here is an easy little pattern I cranked out when my husband needed a new hat. Feel free to give it a whirl. :)
Size - One size fits all
Head size 21" (lightly stretched, fits my head at 23.5")
Depth 8" (If you have a large head, you may need to increase this. Just try the hat on as you go.)
1 50 g ball worsted weight yarn (I used Knit Picks Wool of the Andes in Forest Heather)
1 size US 6/4.0 mm circular needle, 1 set size US 6/4.0 double-pointed needles (if desired, hat can also be worked in magic loop), yarn needle
20 sts = 5" over k4 p4 rib, lightly stretched
*take time to check your gauge and adjust accordingly*
Note: Switch to magic loop or double-pointed needles when knitting in the round becomes uncomfortable, this will probably be around round 3 or 4, but your mileage may vary.
CO 104 sts, join in round, mark beginning of round.
Work in *k4 p4* rib until piece measures 7" from cast-on edge.
Round 1: *k1 k2tog, k1, p1, p2 tog, p1* 78 stitches remain
Round 2: K all K stitches, P all P stitches
Round 3: *k2tog, k1, p2tog, p1* 52 stitches remain
Rnd 4: same as rnd 2
Rnd 5: *k2, p2tog* 39 stitches remain
Rnd 6: same as rnd 2
Rnd 7: *k2tog, p1* 26 stitches remain
Rnd 8: *k1, k2 tog* k1 18 stitches remain
Rnd 9: k2tog 9 times - 9 stitches remain
Cut yarn, thread through remaining 9 stitches twice and draw up tightly to secure, weave in ends.
