I did this with my old tiles: https://www.craftylittlegnome.com/diamond-tile-coaster-tutorial/
Hi Sandy, You could glue them to a thing board and put on waterslide decals to hang on the wall. That way you can have any design you want.
Could you line a serving tray? Or if it's large tile, make a serving tray out of one by super gluing handles on?
How about using them to make the top of a coffee table?
