The table provided has 3 different numbers, one for DK weight yarn and the other two with worsted weight yarn. I have gotten two different gauges with the worsted weight yarn. I have gotten 4.5 and 4 stitches to the inch. I provided a table with both gauges. All the hat numbers have a 15% negative ease already built in. For example, the adult male hat, with 84 pegs at a gauge of 4.5 stitches will yield a tube that is about 18.6 inches. We want a hat to fit snugly, approximately about 10-15%, with a 15% negative ease, this hat will fit a circumference up to 21.4 inches. All the peg numbers provided have also been rounded to a multiple of 4, if you do not need a multiple of 4, deduct or add 2 pegs.
Hat shown in the picture on the right is a DK weight hat using 84 pegs.
This table was updated on 7/8/13 to include DK weight numbers.
