I have included instructions for both Child & Adult sizes...
SUPPLIES: M (9.0 mm) hook, K (6.5 mm) hook, J (6.0 mm) hook and/or I (5.5 mm) hook. The pattern will tell you which sizes you'll need to use, depending on which size you make. You may also want to use a stitch marker.
YARN: I prefer Vanna's Choice for this project, but your favorite sturdy Worsted Weight yarn will be fine.
STITCH GUIDE: HDC = Half Double Crochet, SC = Single Crochet, BPSC = Back Post Single Crochet, ST = Stitch
GAUGE: With K hook, 5 HDC & 5 rounds = 2" [If yours is a little bigger, that's fine.]
[Both sizes] Using M hook, Start with Magic Loop.
Round 1: 10 HDC in loop.
Round 2: 2 HDC in each ST around. (20 HDC)
Round 3: 1 HDC in each ST around. (20 HDC)
Round 4: 2 HDC in each ST around. (40 HDC)
Round 5: 1 HDC in each ST around. (40 HDC)
Round 6: (1 HDC in next, 2 HDC in next) around. (60 HDC)
Round 7-8: 1 HDC in each ST around. (60 HDC)
** Switch to K hook.
Round 9-16: 1 HDC in each ST around. [If you would like your ADULT hat to be EXTRA slouchy, add a few more rounds with your K hook here.]
** If you're making an ADULT hat, switch to J hook now. If you're making a CHILD hat, switch to I hook now.Round 17: SC in each ST around. (60 SC)
Round 18-23: BPSC (not too tightly) in each ST around. [Too complicated? Too fancy? Work a snug SC in each ST instead.]
** If you'd like a wider band, add a couple of extra rounds. If not, fasten off & weave in ends.
Enjoy your super slouch. ☺
