This is a great idea. 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.
Here, off-the-shelf storage bins convey color, pattern, and travel inspiration with the help of old maps, matte-finish Mod Podge glue (which becomes transparent when dry), a paint brush, and a putty knife to smooth out bubbles.
