For this card, I've used the sketch for challenge 61 on Paperminutes:
I've used blue and green, the subject of this week's Colour Create challenge 15 (haven't done the option this time - perhaps another card later in the week).
The Pink Elephant challenge 14 asks for the use of 'light blue, medium or dark blue, green and white', so this fits that one.
And this week's challenge 39 on Cupcake Craft asks for a card for a man or boy.
And, lastly, the new challenge on Created by hand is 'postage stamps' - and as three of them are on this card, I'm linking for that.
The base card is a PDA design, the large picture is from a concept card kit, the fish at the top is a rub on and the three stamps are also rub ons, mounted on DCWV textured card.
