Tiny Owl Knits shares this about her The Parseltongue Hat..."You know, it can get pretty cold out here at hogwarts!  This hat will not only help you understand snakes, it will encourage better relationships with them!   I ssssswear!"

Shown in alpaca suri merino DK weight this hat can also be knit beautifully in a worsted weight yarn.

Gauge for hat: cast on 28
row 1: (P2, C6F, C6B) repeat
row 2: (K2, P12) repeat
row 3: (P2, K12) repeat
row 4: (K2, P12) repeat
row 5: (P2, K12) repeat
row 6: (K2, P12) repeat

Repeat rows 1-6 for just over 4 inches to get gauge.  Relaxed work should be 4 inches wide (omitting your first P2 border) ie: 26 stitches = 4'
However, if you cant stretch it out easily to get 16 sts in 4', get some bigger wool.
