Could you do like Tan suggests, take 1000's of photos of them together and one at a time and then photo shop them onto one card, itms? That is what I will be trying tomorrow! Lots of different places, props (fake pressies, chrissy paper, tinsel, decorations) ect and then hoping for the best! I will just be putting red and white clothes on them all, likely just a green singlet and red nappy cover for DS2, a white singlet and red undies for DD and some red shorts for DS1.
