Why it is called the H2O Hat, I do not know. I think I would have called it the One Hour hat. Or the Pie Hat, as in easy-as-pie. Knit with either bulky yarn or three stands of KW held together and only 23 rows, it knits up fast!
Waiting for the storm to pass and the headache to subside, I knit two hats and started a third.
The first two are knit with three stands of bits & bobs of stash stuff held together while the one on the needles is Knitca Wool Slub. Such fun. While the pattern calls for knitting this flat and sewing a seam up the back, I couldn't see the point of that. Mine are knit in the round. Even more fun.
My goal now is to have a box full of these in various colour combinations to take to the family Chirstmas get together and let the young ladies go at it.
