My kids wanted that we have some 3D ornaments and I was looking for the appropriate materials. The Snöfint coasters were just perfect. Is not too much to say about this idea: you can use 3 or 4 coasters for one ornament, cut the edge off all the coasters, but one. For the one with the edge, just punch a hole so it will be easy to hang it after you are ready. Fold all the coasters in half, glue them, attach a ribbon or a nylon thread and you are done. It takes you less then 10 minutes and about 3 euros for 3 packs of coasters.
