I need to model lots of floor tiles, and I'd like it to look good without costing me a fortune. I've checked Antenociti and I'm not sure their textured sheet materials are quite right for my project. I've considered Hirst Arts also, but I'm afraid it'd be rather expensive (regardless whether I buy the mold itself, or just the casts) and I'm not keen on the 1/4" thickness of the tiles. My experiments with scratchbuilding out of various materials have been unsatisfactory.
So, I'm wondering if anyone can suggest a good way to scratchbuild the tiles, or a good source for cheap, ready-made ones (either separate tiles, or sheets of tile-textured material). I need them for quite a fancy, palatial-looking interior board so they need to look good.
