Materials-Black crochet thread, less than 350g; steel crochet hook size 1 or 2.35 mm; one snap, sewing thread, (optional) wire for hat or stiffener.

HAT
Chain 28 loosely, join to make ring.
Rnd 1-ch 1, sc in each chain (if the stiches are firm enough no stiffening is needed)
Rnds 2-3-ch 1,sc around
Rnd 4-ch1,*sc in next 5 sc, sc next two sc tog* around, sl st to first st
Rnds 5-6-rep rnds 2-3
Rnd 7-ch1,*sc in next 4 sc, sc next two sc tog* around, sl st to first st
Rnds 8-9-rep rnds 2-3
Rnd 10-ch1,*sc in next 3 sc, sc next two sc tog* around, sl st to first st
Rnds 11-12-rep rnds 2-3
Rnd 13-ch1,*sc in next 2 sc, sc next two sc tog* around, sl st to first st
Rnds 14-15-rep rnds 2-3. Continue in this manner until you have can to a point.
I usually make it to about rnd 11, then start spiraling and decreasing until it comes to a point but sometimes I like to be precise.
Brim-connect thread to base of hat,ch 3
Rnd 12 double crochet(dc) in each st, sl st to first st
Rnd 2-dc in each dc, sl st to first st
For a decoration or display hat I repeated rnds 2&3 and then Rnd 5-ch 1 sc around, with a wire under it for shaping. Stiffening works well too.
However for hat that will be safe for little ones but will still stand up, only work rnds 1-2 and then work rnd 5
