You can use plain paper, cardstock or for metal signs to get a glossy finish I use photo paper. Also you can use the full page label and just cut out & stick. You can back the signs with wood, cardstock, foam board, plastic ect. I like to use double sided tape.
As many people have said earlier in this thread, THANKS for all of the signs. I think I need to get moving on my layout so that I can actually USE some of them.
4 more pages First I think your RR logo is realy neat, one of the best that I have seen. I like sharing the signs that I find, please show us all some photos when you put them to use. Here is some I did today.
