Box Jellyfish Crochet Pattern (US)

I had been searching for some crochet inspiration and found that the web is inundated with jellyfish amigurumi! However, I had a good long search and couldn’t find a pattern for a box jellyfish, so I made my own!

I would say this is a project for the intermediate crocheter – someone who has had a little bit of experience of basic stitches – but that doesn’t mean that a beginner can’t take on the challenge! You’ll just have to do some preparatory research into simple stitches and techniques to find your bearings.

I took some technical inspiration from other crochet artists and have included the appropriate links so you can check out their stuff 🙂 Enjoy!


You’ll Need

  • Crochet hook
  • 1 yarn though 3 different shades is preferred
    • I would recommend blues; be careful with lighter colours as they get dirty quickly
  • Stuffing is essential but let’s innovate rather than create a market if we can! If you have an old pillow, duvet or cushion, you can use the polyester filler from that. I have even used and old pair of tights as stuffing – I’m a big fan of upcycling and protecting our earth and our bank accounts!
  • Darning needle is highly recommended, but it is possible (if rather frustrating) to attach tentacles and close the cube without one.
  • Buttons or safety eyes are optional; you can darn eyes and mouth to avoid small parts if this is for a baby or child.

Key Abbreviations

  • sc – Single Crochet
  • dc – Double Crochet
  • ss – Slip Stitch
  • ch – Chain Stitch
  • 3sctog – 3 Single Crochet together (decrease)
  • *abc* – repeat abc until the end of the round

Crochet Cube – Jellyfish Body

This was inspired by Shelly’s “No Holes” Sc Square – Free Pattern and GratiaProject’s Amigurumi Cube so you can check them out!

A miniature crocheted box jellyfish body

You can make your jellyfish body as big or as small as you wish by adding more or less loops in the beginning. Just remember to adjust the ‘length’ of the body to maintain the square shape.

  1. Magic Circle with 8 single crochets (8)
  2. *sc, 3sc in one stitch* (16) The middle stitch of the group of 3 is the corner. I place markers in the 4 corners to make the next steps easier. Use a paperclip or safety pin if you don’t have a crochet marker.
  3. ss to join the round, ch1 & sc into the same stitch. This is the same process for the start of every round.
    *sc in each stitch except for the corners which get 3sc each* (24)
    Remember to replace the corner markers each time.
  4. Repeat Step 3 until you have completed as many rounds as you wish. Every round should have a multiple of 8 single crochets. Boxy has 10 rounds, ending on 80 stitches (19 stitches between corners).
  5. ss to join the round, *sc IN THE BACK of each stitch* This is the transition from the top of the body, to the ‘face’. You can remove your corner markers, but I still use one to mark the round of stitches (80 in my case).
  6. *sc in each stitch*
  7. Repeat Step 6 for as many rounds as it takes to create a square shaped body. Boxy had 20 additional rounds.
  8. Fold the sides of body from the top to the bottom to determine your new ‘corner’ stitches. Remember how many stitches you have between corners as you should still have this many when you replace your markers.
  9. *sc IN THE BACK of each stitch except the corners, which receive 3sctog* This is the transition from the ‘face’ to the underside of the body and the start of the decrease of the square. Remember, the corner marker is the middle of the 3 stitches so make sure and include the one before and the one after when you stitch them together. Replace the marker in the new stitch you have just formed.
  10. *sc in each stitch except the corners which receive 3sctog* Repeat this step until there is just a small opening left in the bottom of the cube. If you want to attach buttons or safety eyes, do so now & add your stuffing.
  11. Continue with Step 10 until you have just 8 stitches left in the round. Use a darning needle to link up the 8 stitches and close the cube.
  12. The skirt is attached in the top stitches that we left in Step 9, in the ‘bottom edges’ of the cube. *3dc in every stitch* though you could get away with 2dc in every stitch for a similar, less crowded effect.

Congratulations on forming the body of your jellyfish!


Curly Cue – Tentacles

Inspired by Handwork DIY’s curly cue video – check it out!

Two-tone blue Curly Cue crochet tentacles

This is where you can incorporate other colours, materials and sizes of yarn if you wish. I used some leftover fleecy yarn that was twice as thick to give 2 fluffy, cuddly tentacles. The other two were in the style of the curly cue above, but much longer.

  1. Begin with a length of Chain Stitches and don’t make them too tight to work in. Remember that the finished length will be almost half what you start with. I used 50ch for Boxy’s tentacles (+3 as you will see in the next step).
  2. Add 3ch, to compensate for the upcoming double crochet.
  3. Go back to the final stitch in the chain from Step 1 and put 2dc in that stitch. The 3ch from Step 2 count as the first dc in that stitch.
  4. Put 3dc in every stitch in your chain. This is what creates the tension and causes the curl. Leave a long yarn tail at the end when you tie off, to connect the tentacle to the body.
  5. If you wish to add more colours, you can start at the tip of the tentacle and put 1sc in each stitch as can be seen in the video above.
  6. Make FOUR tentacles.

Now all you need to do is darn them together!

  1. Using the long tail from Step 4, start closer to the centre of the body and work your way out. The tentacle should end in a corner.
  2. Darn through each stitch at the top of the tentacle and back into the body.
  3. Start with the additional colour stitch, back through the body.
  4. Then the top of the double crochet and back through the body.
  5. Then the bottom of the double crochet and back through the body.
  6. Finally, darn the original chain stitch into the corner at the base of the body.
  7. Check that all areas are securely attached by giving the tentacle a gentle pull. Now, send the darning needle through the stuffing and out through the side of the jellyfish. Tie a knot in it, close to the body, and cut the yarn just above it. Using the flat end of the crochet hook, push the small knot back through the body so it’s no longer visible.
  8. Pull any remaining threads through the body in the same way.
  9. Repeat until all 4 tentacles are securely attached.

Now you have your own, beautiful amigurumi box jellyfish friend!

Boxy, in all her glory.

You can hug this one as much as you like, but just remember to stay away from them in real life – they’re not so cuddly in the ocean!

Job Vacancies & Financial Support (for UK People & Businesses)| Covid-19

With the Coronavirus bringing so many industries to their knees, millions of people around the world are inevitably going to be out of work. Other industries are desperately seeking employees to deal with changing demands, so I’ve compiled a comprehensive list of vacancies (mainly in UK retail) to help make the job search a little bit easier.

I will continue to update this page as more information becomes available.
Latest Update: 30/03/2020

Jobs Vacancies

Here’s a list of some employers with current vacancies – all in one place.
You can narrow the results by adding your location to the search bar.
You can also search for jobs via S1Jobs, Glassdoor, Indeed and more.

Financial Support

Unfortunately, the UK government have provided little concise information at this difficult time. There are people in so many different positions, dealing with zero hour contracts, redundancy, self-induced quarantine or statutory sick-pay, to name a few.

I hope the following links provide some light in this dark time, but more importantly, help people get the support we desperately need over the coming months.

Screenshot from the website
The Redundancy Payments Helpline is back up and running as of 19 March 2020

Support For Businesses

My heart goes out to all the ambitious, talented and passionate business owners who, through no fault of their own, are facing the potential destruction of their livelihoods. Here’s a little advice from the government with, hopefully, much more to come.

Some good news for Scottish Businesses

If you are a business owner and have set up a support fund for your business, please leave a link in the comments.

I will continue to update and add to this page as more information and relief is brought to light. We will make it through this if we work together.

With love, peace, strength and solidarity,

Postcards From Italy

Diary of a Scuba Instructor in Glasgow, Scotland.

Today, I spent several hours chatting to friends and family over different video-calling platforms. In a way, I count myself lucky that this is all happening at a time where we can stay connected through the wonder of technology. It also goes to show that the internet should no longer be considered a luxury – it’s a utility!

So, the plan is to keep communicating regularly, and I’m slowly creating a list of family and friends to call at the same time every week. Where we would have planned to go out for lunch or coffee, we now get that coffee at home, plant ourselves comfortably and spend time chatting, as though we are side-by-side.

After feeling a calling for quite some time, I finally took a few minutes to conduct some Metta Meditation for all the people of our world, offering love, solidarity, strength and peace.
