Spider jar cozy

Spider jar cozy

Hi! Oh my! I just realised it’s soon Halloween and I haven’t posted anything for the holiday yet! I am happy to present the Halloween Spider Jar Cozy! I added little spider babies to the top of the jar. I think they look a little funny and when I was creating this pattern I realised, this is the kind of crochet design that I enjoy the most! I like to add a little humour and funny twists in my creations.

If you like this post,  I would really appreciate if you follow me on Facebook! Then I know that you guys out there like my content and it helps me grow! Thank you!

I am sorry that my pattern is a little late. I feel I’m still hanging behind after we where sick. Also I am trying to translate all my patterns in Norwegian and German, and that takes time too. I have to make each post 3 times, but I get so many additional readers from Germany and Norway and they are all so thankful and happy that I take the time to translate my content. Especially the Norwegians aren’t spoiled with pattens in their own language!

You can fill the jar with candy or a candle, or it can be used for pencils or maybe even your crochet hook collection! I have also written how you can easily make changes if you have a bigger or a smaller glass than mine.

Now let’s to stitch up the spider jar cozy for your Halloween decorations!

I use affiliate links in this post, this means that I get a small commission when you buy something from Amazon. It does not add any extra cost on your part.

This time I used this yarn from Schachenmayr Catania Grey 242 The yarn has a nice shine so it is perfect for this type of projects!

Now, let’s start with the pattern!

Skill level – beginner friendly

Abbreviations used:

A jar. (mine is abound 6 inches/15 cm high and 3 inches/7,5 cm wide)

The pattern is written in US terms

First we will start with the bottom of the jar cosy and work our way up. The upper part is crocheted separately. We will also be making the spider web separate and then the parts are connected thought the spider web.

Bottom of jar cozy

This part is worked in continuous rounds. I advise you to place a stitch marker to keep track of where you are. Place a stitch marker in the first single crochet and move it up as you finish the rounds. Do not join until instructed.

I have written the pattern based on the size of my jar. If you have a bigger/smaller jar you can just add more rounds or stop when your circle is big enough. Just keep it in a multiple of six. Check every once in a while to check of your circle is big enough, You don’t want it to big because then the result won’t look good, you need a little tension to it, otherwise it will hang loosely,

Rnd 1) 6 sc in a magic ring. (6 sc)

Rnd 2) Inc in every stitch. (12 sc)

Rnd 3) *1 sc, 1 inc* (18 sc)

Rnd 4) *2 sc, 1 inc* (24 sc)

Rnd 5) *3 sc, 1 inc* (30 sc)

Rnd 6) *4 sc, 1 inc* (36 sc)

Rnd 7) *5 sc, 1 inc* (42 sc)

Rnd 8) 1 sc in blo (back loop only) (42 sc)

Rnd 9) Chain 3 (count as 1 dc) + 3 ch, skip 3 sc and do 1 dc in the next stitch. *Chain 3, skip 3 sc, 1 dc in next* Join with a sl st on the top of chain 3.


Check to see if the tension is right.

Rnd 10) Repeat round 9

Now we are going to create like a “back wall” on our jar cosy. We are going to crochet up towards the top at only one side. The front side is left open for the spider web. I included many photos so it should be easy to follow the steps.

Rnd 11) Now we will only crochet on the back part of our jar cosy. Decide how wide that you want the back part to be. I Left five “gaps” on the front. But, depending on how big your jar is, you have to adjust this you self. Just keep the front part “window” smaller as the back part.

Ch 3, do 3 dc in the gap and repeat this until you feel that your back part is wide enough. I left 4 gaps for the front on mine, and added the 3 dc cluster in 7 gaps. (total 11 gaps)When you get to the end of your row, do 1 dc in the dc form the previous row. Chain 3 and turn.


Row 12) Chain 4, 1 sc between the next 3 dc clusters, ch 3, 1 sc between the next 3 dc clusters. Repeat this until the end,  I did this 7 times.

Row 13) Ch 3, 3 dc in each ch 3. Repeat this until the end of the row.

Repeat row 12 and 13 until you get to the top. Leave a little space when you get there (1 cm/0,39 inches)

Fasten off.

I got 4 dc rows at the end, yours might be shorter/longer depending on how big your jar is.


Now we will be making the baby spiders that’s going to sit on top of the jar.

Make enough chains to go around the op of the jar. I needed 30 ch.

Row 1) Any amount of chains that you need to make it fit on top of the jar. Join with a slip stitch to form a circle.

Chain 1, 1 sc in each stitch. slip stitch in the first sc.


Rnd 2) 1 sc in each stitch until the end of the round. Join with a slip stitch in the first stitch.

Rnd 3) Fold the part you just crocheted in half to find out where your middle point is.

I added a black stitch marker on my middle point. I skipped two stitches and but red stitch markers there.

The bobble stitches will be added where the stitch markers are. 1 sc in each stitch, 1 bobble in the stitches where the stitch markers are. 1 sc in the stitches between the stitch markers


Slip stitch in the sc where the first bobble is going and make your first bobble stitch here,then 1 sc in each sc, and 1 bobble where your markers are.

At the end of the row, 1 slipstitch in the first sc. Cut the yarn and weave in ends.

Now attach the eyes,


To make the spider feet, simply sew them on with some yarn. I attached the yarn from behind with a tapestry needle, formed a loop and went behind again and attached the yarn. Cut the loops to form the legs.



Join the two parts with each other. Attach the yarn on the one part where the 3 dc groups are. Do a slip stitch in a few stitches away from the spider, chain 3 and do a slip stitch in the sc. Chain 3, skip two stitches on the part where the baby spiders are. Continue like this until the parts are joined.



The spider web will be attracted to the front part.

Spider web

Rnd 1) 14 sc in a magic ring. (14 sc)

Rnd 2) Ch 6, 1 dc in every second sc.


Rnd 3) Ch 8 (first 3 count as 1 dc). *1 dc in next dc, ch 5.* Join with a slip stitch on top of the third chain.

Place the spider web in the middle. Now we are fasting the web with the rest. Make as many chains as you need to get to the first corner. Then fasten with a slip stitch

Do this on all four corners. Make sure that there is a bit of tension there.



When you are finished, weave in ends.

That’s it! I hope you liked the pattern and that it was’t to fiddly! If you have made a jar cozy, you can show me a picture on Facebook or tag me on Instagram. I love seeing your creations! I wish you all a happy Halloween!
