I received a very cool handmade gift for Christmas this year. Nancy, my brother's girlfriend (also known as Fancy Nancy) made these very personalized coasters by adhering the map to a cork coaster. She cut a circle from heavy map paper. I think she printed the maps herself on cardstock, but it is possible she used actual maps. I would think both would work. The circles were then adhered to the cork with acrylic gloss or Mod Podge. The best part of these coasters is that the maps are all close-ups of places I have lived, making it a very personal gift. The are really sturdy and have had lots of use, not only as coasters but as building blocks, wheels, babies and more. Personal and functional are always such a good gift combination.
