Part 1: The Crown
The crown is worked in the round, from the top down.

Starting with your yarn and G/6 hook:
- Rnd 1: Create a magic ring. Ch 3 (counts as 1st dc). Work 11 more dc into the ring. Sl st to the top of the beginning ch 3 to join. (12 dc)
- Rnd 2: Ch 3 (counts as 1st dc). Work 1 dc in the same st. Work 2 dc in each st around. Sl st to the top of the beginning ch 3 to join. (24 dc)
- Rnd 3: Ch 3 (counts as 1st dc). Work 1 dc in the same st. Dc in the next st, 2 dc in the next st. Rep from * to * around. Sl st to the top of the beginning ch 3 to join. (36 dc)
- Rnd 4: Ch 3 (counts as 1st dc). Work 1 dc in the same st. Dc in the next 2 sts, 2 dc in the next st. Rep from * to * around. Sl st to the top of the beginning ch 3 to join. (48 dc)
- Rnd 5: Ch 3 (counts as 1st dc). Work 1 dc in the same st. Dc in the next 3 sts, 2 dc in the next st. Rep from * to * around. Sl st to the top of the beginning ch 3 to join. (60 dc)
- Rnd 6: Ch 3 (counts as 1st dc). Work 1 dc in the same st. Dc in the next 4 sts, 2 dc in the next st. Rep from * to * around. Sl st to the top of the beginning ch 3 to join. (72 dc)
- Rnd 7: Ch 3 (counts as 1st dc). Dc in each st around. Sl st to the top of the beginning ch 3 to join. (72 dc)
The crown is now complete. The diameter should be about 5-6 inches. If you need a larger hat, continue increasing for one or two more rounds before beginning the body.
Part 2: The Body (Lacy Mesh)
Now we will transition to the beautiful lacy stitch, working without increases for the next several rounds to form the straight sides of the hat.

- Rnd 8 (Transition): Ch 4 (counts as 1 dc and ch 1). Dc in the same st. Sk 2 sts, V-st in the next st. Rep from * to * around. Sl st to the 3rd ch of the beginning ch 4 to join. (24 V-sts)
- Rnd 9: Sl st into the ch-1 sp of the first V-st. Ch 4 (counts as 1 dc and ch 1). Dc in the same ch-1 sp. V-st in the ch-1 sp of the next V-st. Rep from * to * around. Sl st to the 3rd ch of the beginning ch 4 to join. (24 V-sts)
- Repeat Rnd 9 for a total of 6-8 rounds, or until the hat is about 6 inches from the center of the crown. This will form the body of the hat.
Part 3: The Brim
Now we will create the flared brim by increasing the number of chains in our V-stitch.

- Rnd 1 (Brim Increase): Sl st into the ch-1 sp of the first V-st. Ch 4 (counts as 1 dc and ch 1). Dc in the same ch-1 sp. V-st-2 in the ch-1 sp of the next V-st. Rep from * to * around. Sl st to the 3rd ch of the beginning ch 4 to join. (24 V-st-2s)
- Rnd 2: Sl st into the ch-2 sp of the first V-st. Ch 4 (counts as 1 dc and ch 1). Dc in the same ch-2 sp. V-st-2 in the ch-2 sp of the next V-st. Rep from * to * around. Sl st to the 3rd ch of the beginning ch 4 to join. (24 V-st-2s)
- Rnd 3: Sl st into the ch-2 sp of the first V-st. Ch 4 (counts as 1 dc and ch 1). Dc in the same ch-2 sp. V-st-2 in the ch-2 sp of the next V-st. Rep from * to * around. Sl st to the 3rd ch of the beginning ch 4 to join. (24 V-st-2s)
- Rnd 4: Ch 1 (does not count as a st). Work 2 sc in the first ch-2 sp. 3 sc in the next ch-2 sp. Rep from * to * around. Sl st to the first sc to join.
Fasten off and weave in all loose ends. Your beautiful sun hat is now complete!
