For the past couple of years I've been using sign language for the action in my alphabetic code. It works great and I love the sign language cards that I purchased a few years ago from learning is expensive, except for the fact that they only show the uppercase letter. So, today I finally made my own. I plan to print them up and glue them onto blue card stock (consonants) and red card stock (vowels). I hope somebody can use them! Thanks for checking them out!
