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
