I know. Enough of the Instagram already...
BUT if you DO Instagram you should play along with the Photo a Day Challenge. It couldn't be easier, and really you could do it on FB or Twitter, whatever. You just take a photo a day using the prompts for each day (see picture below). I follow Fat Mum Slim's prompts because she's kind of awesome. Then you post the picture using the hashtag #photoadaymay. I've done it for two months now and it's really a neat way to be creative on a daily basis.
P.S. I said 'neat'.
