SS Wave Hat works well in wool, or a wool blend. The hat is worked as a modification of Slipped Stitches WAVES (400 knitting stitches, p166) giving the knitter something interesting to do, but keeping the texture simple enough for either gender. This may be considered an advanced beginner or intermediate pattern because you’ll be working with two colors, just one per round, then slipping and twisting stitches. The pattern is offered with options for worsted, light worsted yarn, and in four sizes. This hat takes just a few hours to knit, making the SS Wave Hat perfect for gifts or charity.
