OK, so here's my entry, finally. I'm leaving for vacation in a few hours so this is last minute fo' real. It turned out a bit too green, maybe, but it is the final version. Didn't fit all the activities I would've liked either btw, I was thinking canoes, badminton, buckets full of cloud-berries, blueberries, lingon-berries, black currents, raspberries, strawberries, birthday cake, all kinds of fun stuff... but the canvas was a bit small for that all. :P Anyway, it turned out decent, I hope.
Looking forward to seeing an abundance of other creative entries when I get back!
