I have multiple doll house flooring sheets with textures that I use all the time. You can find them at hobby shops. They even have a small selection at Hobby Lobby. I have seen a hexagon shaped floor tile that would work great if you can find it. I have seen it at Hobby Lobby before. The sheets come in large 14" x 18" pieces! They are recessed on one side and raised on the other. So you have 2 choices! They work great. Good luck!
