My friend Sarah is very proud of hers - it has all sorts of useful extras on it, like The Bible, and a Sudoku App - and other stuff as well.
Two weeks ago, when she was demonstrating the usefulness of her new toy, she lamented the lack of a proper cover.
I offered to make one. The following day, she duly presented me with five plants [three tomatoes, two courgettes] which seemed a very fair exchange. So I have been making covers. This is a bit difficult as I haven't got an I-phone to hand to check the size - but I think I have the right dimensions.
[that's just a piece of paper with a picture of an I-phone!]
Sarah can have the three on the right - the pirate is destined for someone else.
[Various patterns available on the Internet - most suggest a 15cm square of fabric will be the right size when hemmed and seamed]
