Lay a world map over 3 canvas, cut into 3 pieces. Coat each canvas with Mod Podge and wrap the maps around them like presents. Let dry and hang on the wall about 2" away from each other. I also like the idea of adding pins to all the places you've been.
Pretty much the best website ever: knockoff DIYs of retail decor. (anthropologie, ballard design, crate & barrel, land of nod, pier 1, pottery barn, restoration hardware, urban outfitters, west elm, williams-sonoma and others). Truly some of the neatest ideas ever!!
