My sister recently treated herself to a new iPhone a bright lime green one if you please, but try as we might we couldn't find a nice cover for it in the shops. So I made her one. Her favourite colours are pinks and purples, which actually go well with lime green, and as it happens I had some of those very colours in my stash. I had the button in my button box too :)
She loved it and must have shown it off to friends as the request came back for another one, same colours please, but different colour button.
I did the pattern slightly different - just coz I wanted to really.
They are really simple to do if you fancy one yourself. Simply do a chain that fits snugly around your phone, add two chain stitches, then DC (Double Crochet UK) until it is the right length. Stitch up the side and bottom, add a button and a loop of chain to fasten.
