By simply switching stitches and colors your designer has created the surprising illusion of an overlaying hatband on this knitted hat. Knit in the round, it is not a difficult hat to knit but it looks for all the world, like a complicated project. Try it, you'll love it.
Other knitters will ask to learn the secret of creating the hatband look while non-knitters will be flabbergasted that you knit this yourself. This is an easy, quick, intermediate level knitters project.
I prefer to keep my pattern prices low because, as a knitter, I prefer to spend my money on lovely fibers and yarns, I assume other knitters are like minded.. Enjoy.
