OK I am knitting the Chemo Earflap Hat
I am to here:
Begin with a purl row, stockinette stitch straight for 8 (9.5,10.5,12)cm. End with a purl row. For the toddler size hat you will need to increase 1st at each end of the last row (=90st). For the child size hat you will need to decrease 1st at each end of the last row (=96st)
Why would I need to increase at the top of the hat? Is it just to get a good number to work with?
