Free Pattern: Jabby the Friendly Syringe

I was so excited and grateful to recently get a COVID vaccine, I just had to knit a happy syringe! This pattern is dedicated to everyone in the world who worked hard to make these medical marvels happen in a stunningly short period of time.

You can view this free pattern right here, or download it via Ravelry. (If you’d like the PDF and aren’t able to use Ravelry, please email me for a copy.)

You’ll need:
– Fingering-weight yarn in small amounts of 4 colors: Plunger and needle (A), barrel (B), fluid (C), tip (D), plus black
– Set of size 1 US (2.25mm) double-pointed needles
– Small tapestry needle
– Stuffing

Techniques: Knitting in the round on double-pointed needles, I-cord

Finished size: About 3″ (7.5cm), including needle

– Gauge isn’t important—just make sure your stitches are tight enough that stuffing doesn’t show through the gaps.
– You can scale this pattern up with thicker yarn and bigger needles.

A list of pattern abbreviations can be found on my How-to page.

Syringe (plunger, barrel, and tip)
With A, cast on 6 stitches and distribute onto 3 DPNs to work in a round.
Rnd 1: [Kfb] 6 times (12 sts).
Rnd 2: [Kfb] 12 times (24 sts).
Rnds 3 and 4: Knit.
Rnd 5: [K2tog] 12 times (12 sts).
Rnds 6-11: Knit (6 rnds).
Lightly stuff what you’ve made of the piece so far, and switch to B.
Rnd 12: Knit.
Rnd 13: [Kfb, k2] 4 times (16 sts).
Rnds 14-25: Knit (12 rnds).
Switch to C.
Rnds 26-35: Knit (10 rnds).
Stuff the rest of the piece.
Rnd 36: [K2tog] 8 times (8 sts).
Redistribute the stitches onto 2 DPNs to continue working in a round.
Switch to D.
Rnd 37: [K2tog] 4 times (4 sts).
Rnds 38 and 39: Knit.
Break the yarn and draw it loosely through the stitches with a tapestry needle.

With A, cast on 2 stitches onto one DPN.
Knit 6 rows of I-cord.
Break the yarn and draw it tightly through the stitches with a tapestry needle.
With the tail still on the tapestry needle, insert the tip of the I-cord into the tip. Pull it partially inside the piece, then tighten up the stitches that you left loose on the tip. Weave in the loose ends.

Barrel flange
With B, cast on 4 stitches onto one DPN.
Knit 22 rows of I-cord.
Bind off the stitches.

Wrap the I-cord around the bottom of the barrel, and stitch the cast-on and bound-off stitches together. Attach the I-cord to the barrel with stitches going all around.

Pinch the plunger flange flat, and make vertical stitches all around the piece to hold a flattened shape.

With black, embroider eyes onto the fluid with 2 small horizontal stitches for each, placed 3 stitches up from the color change, and spaced 2 stitches apart. Embroider a mouth with one horizontal stitch between and just below the eyes.

Split the black yarn (or use embroidery thread) to embroider a series of longer horizontal lines onto the side of the barrel.

Weave in any loose ends. Enjoy your new friend, and knit one for a health care worker or patient in your life!

  1. You are incredible! This will keep me busy for the confined week end. Many thanks!

  2. My husband is in charge of the Covid vaccine clinics at the hospital he works at. He’s got a collection of knit viruses, bacteria and other contagious stuff in his office – and now has a Jabby to join them! Thanks for the pattern!❤️

  3. I am a beginner knitter and was wondering if you can knit this on STRSIGHT NEEDLES.

    Do You sell this one?


  4. Hi Rita! Yes, this pattern could be converted into flat knitting. The most basic way to do that is to add two stitches to your original cast-on, and purl every other row for the wrong side. Then you’ll need to use mattress stitch to close up the long seam at the back. The I-cord could be knitted flat in stockinette stitch with similar results instead of an I-cord.

    DPNs are definitely optimal for this pattern, though, so if you’re interested in learning to use them, this would be a good project to do that on!

    Wish I could sell you a syringe but I need to keep this one as a sample.

  5. Thank you so much! I must knit one for the lucky one to give me my second shot. You are a genius!

  6. Thank you for such a cute pattern! I just got my first vaccine and have my second one in a couple of weeks. I will bust this out and share with my nurse for the second vaccine. :)

  7. I tried this on circular needles as I don’t have dpns it was difficult at th end. However will try one on straight needles. Thanks for the pattern.
