I've made some coasters out of an old city map of Amsterdam:
You need: map, scissors, ruler, pencil, wallpaper samples, laminator and laminator sheets.
Step 1: Cut 10x10cm squares out of the map.
Step 2: Cut 10x10cm squares out of the wallpaper samples and glue/tape with double-sided tape to the back of the map-squares
Step 3: Put the squares in the laminate sheets. Leave a little space at the sides
Step 4: Let's laminate!
Step 5: Cut out the squares, cut the edges round (you can laminate them again now, to get them to stick together better)
Step 6: Decorate a little box with the map leftovers
Step 7: Put the coasters in and you're done!
Or, as we say over here: Klaar is Kees!
