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. Fasten off.
Block squares.
Layout
Lay squares out in a + shape on a flat surface, as in the diagram below.
Joining
Center Join
As you join the squares, all squares will face RS up at all times. You will insert your hook through only the back loops of all stitches and chains.
First you will join squares 2-5 to square 1, by slip stitching through each chain and stitch around square 1, along with its counterpart on the square opposite.
At each corner ch-sp the first ch will be slip stitched to a chain from the corner ch-sp of the square opposite, then you will chain 1, then you will slip stitch the next chain together with a chain from the corner ch-sp of the next square.
With B and Granny Square Hook Size, place a slip knot on your hook. Always keep working-yarn below squares and hook so that as you work, you are pulling the working yarn from underneath your join.
Begin at the corner ch-sp where squares 1 and 2 meet.
*Insert hook through first ch of corner ch-sp of top square, insert hook through second ch of corner ch-sp of bottom square, sl st, [insert hook through next st of bottom square, insert hook through next st of top square, sl st, insert hook through next st of top square, insert hook through next st of bottom square, sl st] across to next corner ch-sp, insert hook through next ch of bottom square, insert hook through next ch of top square**, ch 1, turn center square 90 degrees to join next square, repeat from * 3 more times, ending last repeat at **, sl st in first sl st to join. Do not fasten off.
Side Joins
Working downward, you will join the side of square 2 to the square next to it. Turn piece so that the sides to be joined are horizontal in front of you.
With B and Granny Square Hook Size, insert hook through first ch of corner ch-sp of top square, insert hook through second ch of corner ch-sp of bottom square, sl st, [insert hook through next st of bottom square, insert hook through next st of top square, sl st, insert hook through next st of top square, insert hook through next st of bottom square, sl st] across to next corner ch-sp, insert hook through next ch of bottom square, insert hook through next ch of top square. Fasten off.
Now you will join the sides of the next 2 squares. Turn piece so that the sides to be joined are horizontal in front of you.
*With B and Granny Square Hook Size, make a slip knot, but don’t place it on hook, insert hook through ch 1 of Center Join that lies at the end of the two sides being joined, pull loop of slip knot up through the ch, insert hook through first ch of corner ch-sp of top square, insert hook through second ch of corner ch-sp of bottom square, sl st, [insert hook through next st of bottom square, insert hook through next st of top square, sl st, insert hook through next st of top square, insert hook through next st of bottom square, sl st] across to next corner ch-sp, insert hook through next ch of bottom square, insert hook through next ch of top square. Fasten off.
Repeat from * to join squares 3 and 4. Repeat once more to join squares 4 and 5, but do not fasten off at the end. Ch 1, and continue to Bottom Edging.
Bottom Edging
Setup Rnd (RS): Sc in top sl st of join, sc in each ch-sp and st to next join*, sc in top sl st of join, repeat from * 3 more times, ending last repeat at **, sl st in first st to join – 36 [48, 48, 60, 60] sts.
Change to Edging Hook Size and ch 7 [9, 11, 11, 11].
Row 1 (RS): Sc in bottom ridge loop of 2nd ch from hook and each ch across, sl st in first 2 sts of Setup Rnd, turn – 6 [8, 10, 10, 10] sts.
Row 2: Sc blo in each st across, turn.
Row 3: Ch 1, sc blo in each st across, sl st in next 2 sts of Setup Rnd, turn.
Alternate repeating Rows 2 and 3 until you’ve completed 36 [48, 48, 60, 60] rows, one for each st of the Setup Rnd.
With hat WS out, with first and last rows of Bottom Edging even, working through both layers, sl st through both loops of first foundation ch and through blo of first st of last rnd, sl st across in each st and ch in the same manner to seam. Fasten off.
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.
