GENEie is a thinking cap for science fans, designed specifically in support of the March for Science on April 22, 2017. DNA Helicies march up the hat and it is really fun to watch the DNA “replicate” as you knit. There are two versions of the GENEie hat, a colorwork version and a cable version.

This hat uses worsted weight yarn in two colors, 130-160 yards total. The sample is knit with KnitPicks Wool of the Andes in Winter Night (Blue – 41 g, 90 yards) and White (20 g, 44 yards).

Finished Size: Adult S/M, 18” around, 8.5” deep

Sizing Notes
For a larger hat, knit at a gauge of 20 sts & 24 rows/4” over the colorwork pattern. The hat as described fits my S/M size head well but is a little snug on my husband’s size L head. He has a hat constructed with the exact same yarn, stitch number and row number with a slightly larger gauge (20 sts/4”, 24 rows/4”) that fits perfectly.

If you just want more length, to add 5 rounds to the length of the hat - either through more 2x2 ribbing or knit round 22-27, then start knitting the chart at round 2.
