Im very new to crochet, but i've written myself a hat pattern already
The shape was based on my partners favourite bucket hat (a plain dark blue cotton hat bought cheap in a supermarket) and he tried it on as I made it, offering suggestions as to how he would best like it. It was very simple to do, only using double crochet (UK term - single crochet in US terminology) throughout.
I wrote up the pattern on my blog, after checking my stitch route.. I havent tested it yet but probably will sometime over the next week or two in different colours. The hat is named after the rocket shaped Zoom ice lollies which come in the same bright colours.
