Chemo Hat #4 is sort of a watch cap type hat in that it has ribbing and a fold up brim. This is the picture of the Wrong Side of the fold up brim (the bottom part in the picture); the Right Side consits of K1P1 ribbing with a right twist in each of the Knit stitches. There is a subtle difference compared to plain K1P1 ribbing. You can kinda sorta see the right twists in the four rounds at the top, which is part of the Right Side body of the hat. Did I just confuse you?
I discovered that joining a round is not something I can do while nursing. I ended up twisting my stitches.
