Pattern is for headsize 21-22 inches
Using thread double, ch 3.
1st rnd: 10 half dc in 1st ch from hook, join with sl st to turning ch. Ch 1.
2nd rnd: * Make 1 half dc in next half dc by inserting hook only in the front loop of half dc, make 1 half dc in same half dc, this time inserting hook only in the back loop (thus making 2 half dc in 1 st to increase). Repeat from * around (20 half dc). Join with sl st to ch-1.
3rd rnd: Work in pattern straight as follows: * 1 half dc in next half dc inserting book only in the front loop of half dc, 1 half dc in next half dc inserting hook only in the back loop of half dc, repeat from * around, thus alternating sts in front and back loops.
4th rnd: Same as 2nd rnd (40 half dc). join as before. Hereafter do not join rnds but work around and around, marking the end of rnds with a safety pin.
5th, 6th and 7th rnds: Same as 3rd rnd.
8th rnd: Increase in every other st.
9th, 10th and 11th rnds: Work in pattern straight.
12th rnd: Work in pattern, increasing in every other half dc only.
13th, 14th and 15th rnds: Work in pattern straight.
16th rnd: Same as 12th rnd.
17th to 32nd rnds incl: Work in pattern straight.
33rd rnd: Work in pattern, increasing in every 5th half dc only.
34th to 39th rnds incl: Work in pattern straight.
Hat should now measure 11-1/2 inches at lower edge (folded width). 1f a larger or a smaller headsize is desired, increase or decrease (to decrease, work off 2 half dc together as 1) as necessary. When hat measures 8-1/2 inches deep, ch 3, turn and with the inside of hat towards you, work 1 rnd of PC sts as follows: * 1 dc in next half dc (hereafter inserting hook under the 2 loops of half dc), 1 PC st in next half dc, ch 1, skip 1 half dc, repeat from * around. Join and fasten off.
Bow. With single thread, ch 25, turn.
1st row: Sc in 2nd ch from hook and in each ch across. Ch 2, turn.
2nd row: Sc in each st. Ch 2, turn. Repeat 2nd row until work measures 9 inches. Then fold work in half having the 1st and last rows come together, and work 2 rows of sc across, to join ends.
This completes one half of bow. Make the other the same. Fold a pleat at joined end of each bow and attach to hat as in illustration. The joined ends of bows are turned under when arranging pleat, and are placed about 1/2 inch apart, giving effect of drawn through slits in hat. Hat may be draped as desired.
