Single Crochet Beanie (as seen on my kids in dozens of previous photos)
Materials:
Worsted weight yarn
Size H or I hook
Chain 3, join with sl st
SC 6 in ring
Rnd 1: 2sc in each sc around, mark beginning of round with tail from chain cast on, 12 sts
Rnd 2: *1sc in first sc, 2sc in next sc; rep from * around
Rnd 3: *1sc in 2sc, 2sc in next sc; rep from * around
Rnd 4: *2sc in first sc, 1sc in next 3 sc; rep from * around
Rnd 5: *1sc in 4sc, 2sc in next sc; rep from * around
Rnd 6: *2sc in first sc, 1sc in next 5sc; rep from *around
Rnd 7: *1sc in 6sc, 2sc in next sc; rep from * around
Rnd 8: *2sc in first sc, 1sc in next 7sc; rep from *around
Rnd 9: *1sc in 8sc, 2sc in next sc; rep from * around
Rnd 10: *2sc in first sc, 1sc in next 9sc; rep from * around
Rnd 11: *1sc in 10sc, 2sc in next sc; rep from *around
Rnd 12: *2sc in first sc, 1sc in next 11sc; rep from * around
Rnd 13: *1sc in 12sc, 2sc in next sc; rep from * around
Round 14 until the hat is the desired length: sc in all sts around and around and around
I hope by this point you see the pattern emerging. I usually go to Rnd 13 for a mans hat, Rnd 11 for a youth or womens hat, Rnd 10 for a childs hat, Rnd 9 for a toddler hat and Rnd 8 for a baby hat.
This is more of a guideline pattern, you can make your first hat and then adjust the crown rounds to your desired size adding increases if needed by doing more rounds in the set pattern.
Enjoy!!
