Antibacterial Travel Mug Cozy

This has been a Spring of graduations. I defended my dissertation on Feb 7, and the next week another grad student from my lab, Marie, defended hers. To celebrate Marie's PhD, I created a travel mug cozy featuring a molecule involved in her research. (Marie doesn't drink coffee, so although this would work as a coffee cozy, I wanted the title to fit HER.) Congratulations Marie!

Disclaimer: This project is called an Antibacterial Mug Cozy because it contains the structure of an antibiotic on it, the yarn and cozy itself does not contain any antibacterial qualities.

  • Size 3 (3.25 mm) double pointed needles
  • Remnants of machine washable worsted weight wool in Pink (MC), Blue (Nitrogens), Black (Bonds) and Red (Oxygens).
  • Yarn needle or crochet hook for finishing
  • Gauge over stockinette: 5 sts/inch, 7 rows/inch
  • Size : Height 4.75" high, 7" circumference.

The Chart

N(beta)EpSmDAP, the active molecule of one of the dapdiamide antibiotics. (30x19 sts)

The Pattern
  • CO 47 stitches of MC
  • Join in the round, K21 stitches, *P2, K2* until last 2 stitches, P2.
  • If you are using three knit needles, arrange the stitches so 21 are on the first, 12 on the second and 14 on the third. The entire pattern will take place on the center of needle 1, and ribbing on the 2nd and third needles (the remaining 26 sts).
  • Round 1: K21 stitches, *P2, K2* until last two stitches, P2.
  • Round 2: K1, work the first row of the pattern (1: Right to left), K1, *P2, K2* until last stitch, P1.
  • Work all 30 rows of the pattern as above, sticking with the same ribbing pattern
  • Work 1 row (K21 stitches, *P2, K2* until last stitch, P2.)
  • Cast off loosely, sticking with ribbing pattern where applicable.
  • Weave in all loose ends.

K - knit
P - purl
SSK - decrease by slipping two stitches then knitting them together. Alternatively, you could slip one stitch, knit one stitch and pass slipped stitch over.
K2tog - decrease by knitting two stitches together.

  1. Actually, if someone used a bamboo yarn, then the yarn would be antibacterial as well. : )

    Also, congratulations!

  2. Ecogryff, you're right, I forgot about that feature of bamboo yarn! I felt it was important to include a disclaimer in case anyone decided to try to make the cozy cure infections... (!)

  3. Congratulations on your Phd!! I'm as proud as if you were one of my own, LOL. I've been following your blog for a couple of years now with MUCH enjoyment and just wanted to say HI.

  4. Thank you! I'm glad you've enjoyed the blog

  5. Rebecca, this was such a thoughtful defense gift; thanks so much! It's fun to see it on your blog too! ~M

  7. Rebecca, thank you for your disclaimer. I actually found my way here from Ravelry to find out exactly why it was called "antibacterial". I knew it would have some potentially protective aspects just because it's a layer between an object and your hand... But it also seemed like it could be because of the funky design. I do love your story!

    And thank you ecogryph for the interesting info about bamboo yarn!
