Notes:

ERRATA: I have updated the pattern to correct an error. All Hdcssflo (Half double crochet slip stitch front loop only) should just be hdcss (Half double crochet slip stitch). I also added finished measurements for the hat when laid flat before seaming. The revised pdf is now available.

ERRATA: Round 3 CINCH closed, not INCH closed

ERRATA: Row 25 should read:(ws), cont. w/A, ch 2, 2dc in first st, sk 2 sts, sc and 2 dc in next st, rpt() to last 3 sts: sk 2 sts, sc in top of ch 2 of previous row, (33 sc, dc, sc groups), TURN
