It's Wheely a square.... free crochet square pattern

Sorry, yes I know that's a rubbish title.  But it's the best I've got at the moment,and it will have to do.  So, would you like to know how to make the square?  Then I'm about to share the instructions. I made this last night for the CAL we're having on the New Zealand Nappy Network forum, basically we're doing a different block each week, and this week is my turn.  I'm doing the instructions twice too, firstly with US terms, as most people seem to use those now, and then in British terms, which is what I prefer, seeing as it's what I learnt with. (If you're not sure what you know, then a good guide is that US uses single crochet, British doesn't, so if you know what a single crochet is, the chances are, you know US terms).

US terms
You will need, 
Yarn in various colours, for both squares I used 8ply/dk yarn.
A crochet hook that suits your yarn, I used a 4mm hook.
A needle to weave in ends.
And a bit of spare time.

I love to see finished items made from my patterns, so feel free to pop along to my facebook page to share, I think that this would make a great blanket with all the squares fastened together.
