mobile casey and stripy jack

Mobile Casey and Stripy Jack are mobile phone cases or jackets. I initially made Casey (right) as a birthday present for Mike. I worked on him on the subway and on my lunch break at work so Mike wouldn’t know. He’s a big fan of the Ugly Dolls, so Casey and Jack are kind of like fan art, I guess. Mike loved a cellphone-eating monster but it was a bit too snug for his iphone, so I ended up remaking the design and created Stripy Jack (left), who fits the iphone perfectly.

Casey, however, fits my phone perfectly. And I have a really basic phone that is 1 3/4″ wide, 4 1/4″ tall, and 5/8″ thick. So the smaller pattern may fit a phone with similar dimensions.


Mike wanted the top part to be able to flip back completely…

so he can use it like a sleeve, plug in his earphones, and put it into his pocket. So Casey and Jack were designed around that idea.

To make your own mobile phone-eating monster, you’ll need some worsted weight yarn (I used acrylic because it’s nice and durable) and a 3.75mm hook. And a bit of felt and sewing needle and thread for eyes and teeth.

It’s really rather straightforward and size is easily adjustable.

For Casey (the smaller monster):

Row 1: ch 15, 1 sc in 2nd ch from hook, 1 sc in each ch across, turn.

Row 2: ch 1 (does not count as 1 sc), sc in each sc across, turn.

Repeat row 2 until piece measures 11 inches, fasten off.


Fold the bottom short end up to the 7th or 8th row down from the top, like so…

Fold the top 7 or 8 rows down, like so…

Secure the folds with pins and crochet the two long sides together. In the top part where there are three layers of fabric stacked together, crochet through all three layers.

(You can also sew the sides together, but I find crocheting creates a more sturdy seam. With sewing, you may want to consider reversing the folds i.e. folding the top down first, then fold the bottom part up, and then turn the work right side out when finished.)

Cut out teeth from felt and decide on placement. It’s best done with the phone in it, so you can see how much the top of the teeth and the front flap need to overlap (I didn’t have the phone in mine but it worked out).

Sew teeth to the piece behind the front flap, and eyes to the front flap.

Because when the front flap flip backward it will leave the stitches behind the eyes exposed, here’s a way to hide the sewing stitches behind the crochet stitches (the tutorial is for sewing a lining to a crochet bag, but I hope it helps!). And here we have it, Mobile Casey! :D He looks concerned for some reasons… hmm.

Now for Jack (the larger iphone-eating monster):

Row 1: ch 17, 1 sc in 2nd ch from hook, 1 sc in each ch across, turn.

Row 2: ch 1 (does not count as 1 sc), sc in each sc across, turn.

Repeat row 2 until piece measures 12 inches, don’t fasten off.

Jack needs more head room so it can be flipped backward more easily, so it needs short rows on either side of his head, as follows:

Row 3: With hook and yarn still attached to one corner, ch 1, sc evenly down the long side, turn,

Row 4: ch 1, 1 sc in each of next 8 sc. Fasten off.

Row 5: Attach yarn to corner diagonal from beginning of Row 4, ch 1, sc evenly down the other long side, turn.

Row 6: ch 1, 1 sc in each of next 8 sc, fasten off.

When the side rows and short rows are complete it will look like this:


Fold the bottom short end up to the bottom of short rows, like so…

Fold the top down, like so…

Secure all layers with pins and crochet the long sides together. Sew on eyes and teeth. And here’s Stripy Jack! :D

Enjoying an afternoon snack…


Pretty easy, eh? Feel free to drop me a note if you have any questions!

Happy Thursday! :D

  1. I made one, But it was WAY to big, ( the ipod one )
    What size yarn did you use?

  2. wow, you’re quick! i used worsted weight yarn and a 3.75mm hook. it does have a bit of room around it, especially headroom, so it flips easily. but i also have a pretty tight tension. what size did yours turn out?

  3. Way to big hahha xD It could have fit one and a half ipods.
    I used the same yarn, but not the same hook,
    xD I may have to make some alternations for myself, I don’t have a 3.75 hook.
    And I know, I’m a fast crocheter xD

  4. if you use a larger hook then yes, the end product will be larger than the one i made. thank you for trying it out! :D

  5. I just made another one, and now it fits perfect :)
    But being the idiot, I am, I put the face with the flap the wrong way :/
    OH WELL!
    It’s still cute :)
    Thanks for the pattern.

  6. This is just one of the coolest ideas I have seen for a phone case!!! I LOVED it and have been busy posting it to all of my family to see — even those who can’t crochet. I suggested these to my Mom, who lives on a fixed income, as a great way of using up her stash yarn and making Xmas presents that everyone would love. Rarely does a pattern really grab me, but this one did — it is just soooo fun.

  7. Fab pattern! So easy to make ‘n’ adjust! Just started small production for X‑mas market in me man’s school. Kiddos gonna luuuuuv them:) Thanks a million!!

  8. I was wondering how you made Jack have stripes. It looked like different colors so i was confused. Thanks!

  9. jack does have stripes :D i crocheted two rows with the lighter green and then changed colour and crocheted two rows with the darker green, and continued alternating two rows of lighter green and two rows of darker green until i have a long enough piece. if you need instruction on changing colours in the beginning of a row, this tutorials may be helpful:

    hope that helps!

  10. I am now making jack, but it the sides keep ending up crooked and I have to go back and fix it, I would almost have him done by now if it weren’t for that. Im not sure if im doing something wrong or not. I have the right yarn and needle, so I was wondering if you had any tips. If not its fine. Thanks!!!

  11. hmm. everything will be ok as long as your stitch count on each row is correct. when i first started crocheting i always got confused about whether i should crochet in the very first stitch in each row. for jack, begin each row with a ch 1 but it doesn’t count as a stitch, so make sure to make an sc in the very first sc of the row. then when you reach the end of the row, sc into the last sc, but don’t sc into the turning ch 1 from previous row. 

    if the stitch count is correct and the sides still look wonky maybe it has to do with tension. that can be fixed but tucking and pulling it a bit afterward. and after you sew the front and back together the sides will look more straight.

    hope that helps!

  12. hi! i found your blog through tangled happy, and i love the phone covers…sooooo cute! i’ve pinned you to my crochet board so i won’t forget…i’m going to make a couple of these as gifts! thanx a lot!
    take care!

  13. Do you sell the mobile casies? If not then you should definitely consider it. Its amazing and perhaps more reliable and customisable than the one you get in the market.
    Good Job!

  14. hmmm… definitely give it a try! you can do a 19 ch and then do a couple of sc rows, then measure it against the width of your phone. if it’s slightly longer than the width of your phone then it should fit. hope this helps!

  15. Hi, I found your blog when I was looking for a beginner’s crochet project. Your pattern was really easy to follow and now I have my own pink monster to protect my phone. The only adaptation is that I glued rolling plastic eyes on my monster.
    I put a photo of my creation on my blog (it is in Danish, sorry) and I linked to your blog for pattern details.
    Thanks for the inspiration :)

  16. Love your designs the strpey jack iPhone you made with the flap
    What does the diagonal actually mean in instructions
    And how would you make it longer and then the flap
    Please email me if ya can again love your cozies thanks

  17. Nice phone designs trying to make the Casey stripe and jack one
    What do you mean in directions rotate at an angle as never seen that written like that
    Also if you wanted to make it longer how would you do that and the flap or would the flap still stay the same again beautiful designs and nice site please email me thankd

  18. Hi Pat, thank you for trying out this pattern! So, your question about where “diagonal” and rotating was mentioned — after you finished crocheting the case to 12″ or desired length, turn the piece sideways, then do rows 3 and 4, in which you crochet up and down one of the long sides of the case. You would then fasten off the yarn, and the re-attach the yarn to the other long side, and then crochet up and down the other side of the case. You can make both the case and the flap longer by repeating row 2 for as many times as you like. You would do a few more sc’s in row 4 if you want a longer flap. Hope this helps!

  19. Thanks so so very much as cleared this up for me just never seen diagonal etc Love this design as its not opened etc and its closed do you have any other phone cozie patterns also just to clarify the flap if you want bigger syou would just do the 8sc right or not just love this

  20. Hi Pat, you’re so welcome! it depends on the size of the case you’re making, i think doing 8sc would be enough though, if the flap is too long it’s difficult to open. i don’t have another phone case pattern at the moment, but maybe in the future :)

  21. One more question when you sewed the sides up etc I mean crocheted them did you whipstitch or sc or what thanks

  22. Hi there! I love this pattern and I was wondering if I could make some slight changes to it,(I want to revise the pattern a bit so it can be worked in continues rounds instead of sewing up the sides becuase I’m lazy) I also might be creating a blog in the near future, would it be okay to post your pattern on my page with full credit to you and your link? My goal for a blog is to make a site where all the patterns are free becuase its nice not to have to buy all the cute patterns. Thanks and hope to hear from you soon!

  23. Hi Kali, thank you for visiting my blog! you are welcome to post the link to my pattern on your blog, i just ask that you don’t repost the entire pattern on your blog. you can also describe how you’ve modified my pattern to suit your needs, but again please don’t repost the entire pattern, please post the link to my pattern only. visitors to your blog can simply click on the link to my pattern and get the pattern for free. thank you for asking! :)

  24. If you want to assure the right size, have your phone by you when you make the chain. Make the chain about the width of your phone and continue, adjusting the whole project the same way. It is not hard. I am doing it for a 1 by2 flip phone.

  25. Hello I’ve been looking for a pattern I could use for my iPod touch but I can’t seem to get it right I’m using a thicker yarn (a worsted 4 ply yarn*peaches and cream yarn so cute and not that expensve as so many other yarns are to give it more of a buffer if it were to drop and a 5.0 mm but I can’t seem to make it work could you give me some tips on how to make my iPod touch actually fit because I absolutely adore this pattern the dimensions are 2 and 1/4th inches wide and 4 and 6/16th inches wide sorry I’m not the best at measuring when it’s past the 4th marks any help would be greatly appreciated.

  26. Hi Madison, thanks for giving the pattern a try! I’m not sure what you mean by not working though… If you’re using a 5mm hook, I’d imagine that your phone case will turn out too large. Try using a 3.75mm hook as indicated in the pattern with your worsted weight yarn, and following the pattern for Jack the larger phone case (which was made for an iphone 4, which is similar in size to your ipod touch), it should work out. Hope this helps, happy crocheting!
