This is a herringbone patterned hat that is knit as one piece in the round with a reinforced brim and no ribbing.

To change hat size, decrease or increase needle size (or even yarn weight) as needed to achieve desired size. For example, you can reduce the cast-on needles size to 3.0 mm and needles for the body of the hat to 3.5 mm to achieve a somewhat smaller, adult medium sized hat.

If you need to more substantially alter the hat size then you should decrease or increase in increments of 14 stitches.

The body of this hat is knit with a sport weight wool yarn and size 4.5 mm needles. However, a DK weight wool yarn and 5.5 mm needles achieved approximately the same size hat for me.

I used about 160 yards of sport weight yarn for this hat.

This hat was designed to match with the Kaarna fingerless gloves by Pauliina Hurme / Tukuwool. On the increase stitch, this pattern knits into the back and front legs (kbfl) of the next stitch in the same working row. The Kaarna creates an increase by knitting into the back leg of the stitch in the row below the next stitch in the working row and then into the front leg of the next stitch in the working row (krl). If you are knitting them as a set simply choose one method or the other and knit both projects in the same manner. Both methods look good, but are slightly different looking.
