FO: Top-down knit hat for baby

The hypothetical hat pattern worked!

(Everything looks cute on a baby, don't you think?)
(Definitely cuter than on a roll of paper towels, viz.:)

Specifics for this version:

Yarn: Lion Brand Cotton-Ease (cotton-acrylic) in Lime. (This yarn was such a pleasure to knit--I loved the feel and color both.) One skein can probably make at least 2 baby hats.

Needles: 5mm and 4.5mm needles for knitting in the round (e.g., 2 circulars, or a set of double-pointeds)

Gauge: 5 st/inch in stockinette on the 5mm needles

Fits actual head size (with a little room to grow) as follows:
circumference=16"
eyebrows-to-base-of-head measurement=11" (laying the tape measure over the top of the head)

Using the larger needles, CO 12 sts using Wrap (aka Figure-8) method and join to knit in the round.
Rnd 1 and all odd rounds: Knit.
Rnd 2 : *K1, Kb&f, repeat from * around. (18 sts)
Rnd 4: *K2, Kb&f, repeat from * around. (24 sts)
Rnd 6: *K3, Kb&f, repeat from * around. (30 sts)
Rnd 8: *K4, Kb&f, repeat from * around. (36 sts)
Rnd 10: *K5, Kb&f, repeat from * around. (42 sts)
Rnd 12: *K6, Kb&f, repeat from * around. (48 sts)
Rnd 14: *K7, Kb&f, repeat from * around. (54 sts)
Rnd 16: *K8, Kb&f, repeat from * around. (60 sts)
Rnd 18: *K9, Kb&f, repeat from * around. (66 sts)
Rnd 20: *K10, Kb&f, repeat from * around. (72 sts)

Place a marker to mark where rounds begin (and end). Knit straight until piece measures 5 inches from cast-on.

Change to smaller needles, K1 P1 for 3 rnds.

BO using tubular cast-off.
