We are really starting to introduce Molly to letters, and I was looking everywhere for nice, big, printable letter to hang in her playroom. The nicest ones I found were from Wondertime. They are very clear, and have a picture to go along with them. They also have just enough color, and don't take up much ink to print. I love them, if you need letters, you should check them out at their website!
To Protect them and make them interchangeable, I also hung them in clear plastic sleeves!
