A beanie-style hat for organic chemists everywhere.

Knit in the round, using dk/sport weight yarn on 3.75 mm needles, incorporating 4 important molecules. If you aren’t familiar with stranded colour work, read Theresa Vinson Stenersen’s tutorial on knitty.com.

18 March ‘08 - my original chart misrepresented serotonin (with an octagonal hetero- ring instead of a hexagonal carbon only one), and penicillin had the same octagon-for-hexagon error. I have now amended the chart and uploaded a new version on the pattern’s blog post. This new versionaudreym_080318_heterocyclic.pdf replaces the original

Heterocyclic molecules have atoms other than carbon (hetero-) in a carbon ring structure (-cyclic). The molecules on this hat are penicillin, serotonin, caffeine and theobromine (chocolate!).

I’m new to pattern writing and chart design so please let me know if you come across any mistakes.
