Bacilysin Beer Cozy Knitting Pattern

Today my friend Sarah is defending her dissertation. She is the last graduate student in my lab (our PI is going to retire) so the celebration is going to be huge. Like Marie, I wanted to send Sarah off with something to remember these graduate school years; a molecule knitting pattern that is relevant to her project. Bacilysin is a peptide based antibiotic, so this is an "antibacterial" beer cozy.

Bascilysin Knitting Chart: 39x21 stitches

Materials Required
  • Remnants of worsted weight yarn.
  • size 3 double pointed needles
  • Gauge: ~ 12 sts/2 inches; 17 rows/ 2 inches (The gauge is not critical as long as the cozy will fit around the beer bottle you care about.)
  • A beer bottle to check the desired height

  • Cast on 45 sts in the main color (The cozy is knit from the top down)
  • Work in (k2, p1) rib for two rows
  • Knit 2 rows even in MC
  • Starting with the bottom row of the chart, and working from right to left, knit the 21 stitches in the first row of the chart. Finish the round by knitting 24 stitches in MC.
  • Work the remaining 38 rows of the chart in the same manner.
  • K 2 rounds even
  • *K7, K2tog*, repeat 5 times across. (40 sts)
  • K1 round even
  • K1, *K1, K2tog* Repeat from * 13 times (27 sts)
  • K1 round even
  • K2tog across until the last stitch, K1 (14 sts)
  • K2tog across (7 sts)
  • Cut yarn, pull through remaining stitches and weave in loose ends.
  • Put the cozy on a beer bottle and admire.
When I am working on these molecule knitting projects, I knit the molecule as I am knitting the rest of the cozy (see picture below.) If you prefer, you can knit the entire cozy and then use duplicate stitches to put the molecule on the cozy.
