Julie's Highway Hat

I heard this hat described on a Savvy Girls podcast(episode 59).  I thought it sounded both very cute and easy to do.  After searching Ravelry, and a little experimenting, I have come up with my interpretation of the "Highway Hat".    

Materials needed:

Cascade 220 superwash, or other light worsted weight, in small amounts of green, black yellow and sky blue.
One skein of each will make two or three hats, possibly more, I haven't tried to measure that closely.

US size 7 dpns or circulars, according to your preference (dpns, two circ's or magic loop)

a couple of race car buttons.  (I found mine on clearance at my local,  Jo-Ann  fabric and craft store.) or other car or truck buttons or pins, according to your preference.

Size: child, I made it for my grandson,  finished measurements were about 18 inches around and 8 inches tall.

Gauge: 5 stitches and 6 rows to the inch, measured over St St.


Pattern:
Using green, loosely Cast-on 92 stitches, join into a circle, being careful not to twist, and work in k2, p2, for 10 rounds.

Change to St St, increasing 3 sts evenly spaced around (95 sts)
Work 4 more rounds St St, and break green yarn

Change to yellow and knit 1 round, break yarn

Change to black and knit 5 rounds, do not break yarn

Add yellow, and work round as follows: (k2 black, k3 yellow) around, break yellow yarn

Knit 5 more rounds in black, break yarn

Change to yellow and knit 1 round, break yarn

Change to light blue, and knit 11 roounds, do not break yarn

Add yellow, and knit 2 rounds as follows: k3 blue (k1 yellow, k4 blue) around to last 4 stitches, end with k1 yellow, k1 blue. Be sure to carry unused yarn LOOSELY on the wrong side

Next 2 rounds: k2 blue, (k3 yellow, k2 blue) around to last 3 st, end with k3 yellow. break blue yarn

1st dec round: using yellow, (ssk, k3) around (76 sts)
 Work 2 rounds even

2nd dec round: ssk, k2 around (57 sts)
Work 1 round even

3rd dec round: ssk, k1 around (38 sts)
Work 1 round even

4th dec round: ssk around (19 sts)
5th dec round: ssk around, end round k1 (10 sts remain)

Break yarn, and draw  through remaining stitches to finish off.

Weave in remaining ends, and sew buttons onto roadway.
