Denim cell cozy crochet pattern

Abbreviations:  

sc: single crochet
inc: 2 sc in one stitch
dec: 1 sc over two stitches through the back loops

I used a light blue and a white yarn together to make that denim effect.

 Make a chain with 9 st (You can also measure the width of your sell & make a chain as long as the width):

R1: sc in second ch from hook and inc around (30) *don't worry if it's a little curly when you finish the 1st round!

R2 - 18: sc around in the back loops only (30)

R18-21:  Two st before you reach the right edge of your cell phone case (14th st) chain 21 and connect that chain to the 20th st (counted from that 14th st you started a chain from) (30)

R22-26: continue sc around in a back loops only. When you reach the edge of round 25 *dec, sc until you reach the other edge then dec*. Repeat ** once again. Then finish it off leaving a long tail. Turn the top of your cell backwards and sc trough both layers until you close the gap. Finish it off. 

Now cut off a peace of purple felt in a heart shape and stick it with a glue or sew it to the top of the sell cozy!

For the other cell cozy (in the right picture) is the same until you reach R21:

Make a chain with 9 st 

R1: sc in second ch from hook and inc around (30)

R2 - 25: sc around in the back loops only (30)
R26: sc around in back loops until you reach the middle of the back side of your cell cozy. Then make a chain as long as you want your loop to be. Then sc in the next st you start the chain from and sc around until you reach the start point of your chain again. Then finish it off & hide the tail.
Take a blue button and sew it in the middle of the front side of the cozy in a height you want it to be.

You're done! Easy, isn't it?!  :)
