Granny Square (make 5)
Notes: Work only the number of rnds designated in the table above under Granny Square Rounds. Use color A for all but the last rnd of the square. When you have finished all but the last rnd, fasten off A. Join B with sl st in first corner ch sp, then work last rnd as written.
With A and Granny Square Hook Size from table above, make a Magic Ring by wrapping the yarn around the first two fingers of your right hand one full time. With your left hand, carefully grab both strands where they meet and pull the ring off your right fingers, place your hook through this ring, yarn over, pull up a loop, and you are ready to begin Rnd 1.
Rnd 1: Ch 2 (does not count as a st), [3 dc in ring, ch 2] 3 times, 3 dc in ring, pull tail of Magic Ring to close center hole, hdc in first st to join (hdc counts as corner ch-sp) – 12 dc.
Tip: If you are going to attach a pom to the top of your hat, leave the Magic Ring of one square just the tiniest bit loose and use it as the top square in your hat. This will make it easier to pull the elastic loop of the pom through the center of the square.
Rnd 2: Ch 2, 3 dc in corner ch-sp, *skip next 3 sts, (3 dc, ch 2, 3 dc) in next corner ch-sp, repeat from * 2 more times, skip next 3 sts, 3 dc in next corner ch-sp, hdc in first st to join – 24 dc.
Rnd 3: Ch 2, 3 dc in corner ch-sp, *3 dc in each sp between 3-dc groups to next corner ch-sp, skipping sts between the sps, (3 dc, ch 2, 3 dc) in next corner ch-sp, repeat from * 2 more times, 3 dc in each sp between 3-dc groups to next corner ch-sp, skipping sts between the sps, 3 dc in next corner ch-sp, hdc in first st to join – 36 dc.
Rnd 4: Ch 2, 3 dc in first corner ch-sp, *3 dc in each sp between 3-dc groups to next corner ch-sp, skipping sts between the sps, (3 dc, ch 2, 3 dc) in next corner ch-sp, repeat from * 2 more times, 3 dc in each sp between 3-dc groups to next corner ch-sp, skipping sts between the sps, 3 dc in next corner ch-sp, hdc in first st to join – 48 dc.

Finishing
Weave in all ends.
To attach a pom, sew a ½ inch button just inside top center of hat. Use crochet hook to pull elastic loop of pom through center of top granny square and secure it around button.
If the pom has two ties, pull them through two different spaces on either side of top center and tie in a bow inside hat.
Always remove poms before washing.
