Lay a world map over 3 canvas, cut into 3 pieces. Coat each canvas with Mod Podge and wrap the maps around them. Let dry and hang on the wall. Then add pins to all the places youve been.I need to do this w/ the Titlow Map diy-crafts
Michael Tompsett 'World Map - Paint Splashes' Canvas Wall Art - Beyond the Rack Final piece idea maybe. I like how it's has been done messy but then the stencils make it look very neat. It goes really well with the title.
You could hang pictures of pictures from your trip on the location. Not sure how it would look on a neutral-colored wall, but the idea is great. You could probably spray paint the cork and get a cool effect.
