Make a banner/bunting from photos. Great for anniversary, milestone birthday (I'm thinking of doing this to celebrate a five-year old's birthday, with pictures since birth). (Credit: http://pinterest.com/wineinajug/party-wedding-decor/)
My siblings and I made this for my Dad's 70th birthday last week. Found the letters on a website and emailed everyone and we all colored them and took separate pics. Then we put it on a canvas..BIG HIT!!!
