If you can try to find someone who can use a jigsaw, (or cut them yourself.). We made a simple sketch of a basic shape, then cut them out of wood.
Prime the wood with a pva glue (this stops the tile adhesive soaking into the wood). Let this dry for an hour. Once dry, make sure you have a tile cutter and enough tiles by your side ready to start. Cover the board with tile adhesive, then trim your tiles to the right sizes and push them down into the adhesive, let it dry over night.
Brush white grout over all the tiles and let it dry, then wash it off with a damp sponge, any air bubbles can be filled in with some more grout at a later date. If you want make them waterproof, you can buy a special waterproofer.
A lovely gift, or something to decorate the home.
