knitting a fairy cup cozy

Do you love drinking from mason jars as much as I do? Isn't it nice to have a cozy to protect hands from hot drinks?

I've sized these cozies for an 8 oz. (240 ml) jar -- just right for warming small hands around little wintertime cups of cocoa. And these cozies are quick to knit up, so you might think of making a few as you work your way though your holiday gift list...

For this project you will need a few yards worsted wt. wool: I made three cozies: one from Noro Kureyon, another from Knit Picks Wool of the Andes and a third from Knit Picks Chroma worsted. You will also need a stitch marker (optional), a tapestry needle and a tiny, 3 cm “baby/bee” size peg doll (please check the CRAFT SUPPLY RESOURCES page on this blog for places where you can order blank wooden peg dolls by mail).

US 5 (3.75 mm) dpn needles
US 7 (4.5 mm) dpn needles
(or whatever needle size you require for gauge)

5 st/ 8 rows per inch. Please use which ever needle size will achieve the gauge.
Note: as you are knitting, the cozy might seem too small; please trust me that it will stretch to fit your jar.  It should fit snugly.

CO: cast on
k: knit
k2tog: knit 2 stitches together
Kfb: knit one in front and one in back of st to increase
p: purl
rnd:- round
st:- stitch

CO size 5 needles, use long-tail method (or other method) CO 36 st.  Evenly divide between needles and join in the round. Place marker to indicate start of row/round (optional).

Rnd 1-6:  knit 1x1 ribbing (k1, p1) for ¾ in
Rnd 7-28: switch to size 7 needles.  Knit in stockinette. 2 ¾  in (approx. 21 rnds)
Rnd 29: purl all st. (i.e. 1 rnd garter st)

(knit in the round on dpns)
Rnd 30: *(k2, k2tog) Repeat pattern through entire round (27)
Rnd 31: knit all st
Rnd 32: *(k2, k2 tog) Repeat for entire round (21)
Rnd 33: knit all st
Rnd 34: *(k1, k2 tog.) Repeat for entire round (14)
Rnd 35: knit all st
Rnd 36: *(k2 tog) repeat to end of round (7)
Cut yarn and thread end through a tapestry needle.  Run needle through all st. and secure end.


Count up 3 stitches from the purl (garter) row. From left to right, pick up 5 st. using size 7 needle.
Row 1: knit all st
Row 2: purl all st
Row 3: k1, Kfb, k1, Kfb1, k1
Row 4: purl all st
Row 5: k 1, Kfb1, k3, Kfb1, k1
Row 6: purl all st
Row 7: k1, k2tog, k3, k2tog, k1
Row 8: purl all st.
Row 9: bind off, cut yarn and thread yarn through a tapestry needle.
Sew up sides of pocket so that the interior width of the pocket is 5 stitches wide. Weave in all ends.

Have you created a cozy from this pattern?  I'd love to see your photos posted here on Ravelry!


  1. Hello,
    It's very beautiful and I think it could be a very nice Christmas present. I don't know how knitting but your creation give me to learn.
    Bravo et merci de nous montrer de si belles et poétiques créations.

  2. What a sweet idea wish I knew how to knit. I love mason jars and I found the lids with a straw opening and straw at Michaels so no spills. I use them for my grandchildren and they love them.

  3. I don't know how to knit but really enjoyed your work :) super cute! wish i could make one

  4. That is just adorable! Thanks so much for infusing craft schooling Sunday with such wholesome cuteness! My son is sitting next to me and said "write to her that my kids like very much!"

    1. It's for an 8 oz. (235 ml) jar. I should have made it for a 16 oz. jar (my fav size for drinking tea), however, in the back of my mind, I was imagining this project as a gift for a child, hence the smaller size.

  6. My sister in law made me 4 of those and i don't have the smaller jars. You should post some larger ones.

  7. If I wanted to make it for the 16oz mason jar, could I just double the pattern?

    1. Hi Brittany -- I'm not sure doubling the pattern would translate exactly to the correct size for a 16 oz. jar, but it's worth a try! Maybe cast on, knit about 10 rows and see how it fits? (Also, keep in mind that there are 2 sizes for 16 oz. jars -- regular mouth and wide mouth.)

      I don't have time this week to test out a larger size, but perhaps by December I could post a pattern for a larger jar-cozy.

      Please let me know how it turns out if you test it.

  8. Thanks for sharing the pattern. It's hard to find those with a base knitted in. I'm making these a little taller by increasing the number of rows of ribbing. I freeze in many Mason jars and these will help protect all of the glass surfaces, but i can also find down the extraribbing and use for drinking as well. Nice and easy pattern!

  9. Can circular needles be used instead of dpn?
