Are there large size signs that could be used as labels on a module? I'm looking for something that can be positioned to lay flat on the tile. I know there's individual letters that can be used, but that's time consuming, putting down one letter at a time. Dave Snow has some warehouse signs, but they are too small. I need the same thing except with letters about 3 times the size. Any ideas on where3 to find such signs would be much appreciated.
