This hat is knitted on my Brother KH950 knitting machine with some nice soft suerwash merino yarn. I start with needles 86 L - 86 R and do a selvedge with tension 0 (3 rows). Then knit rib, knit the main part of the hat and waste knit. Gather the stitches onto a double thread, before tightening sow up the seam as this will be easyer to do before tightening in the top. Tighten to as tightly as possible (there will be a small gap at the top) and fasten all ends.
