Granny square crochet hook holder

OK, this ain't gonna win any awards but I was fed up on having to search around for my hooks and I am too busy doing other things to crochet a hook holder...so I dug out this granny square that I got as part of a assortment of yarn odds and ends at a charity shop and stuck my hooks in. It works great!
The granny square is quite stiff and the hooks fit in snugly. I suppose if I had more of those granny squares I could stitch them together to make the holder bigger and perhaps put a flap on it too...
