Jean they are on yardsticks. I stained them, and thinned down red paint. They were 68 cents each at Lowe's. Hot glued the letters down. Tacky glue did not work , the letters fell off. The one made with the bell on it was my first one made on a popsicle stick. like the rulers much better.
Don't go to Ebay to buy the tiles if you can't find them. Hasbro.com sells the setd for $6.99 free shipping if you live in the right state. They go for a lot more on Ebay or Etsy.
