Art Word Wall

This year I'm trying out something new with a bulletin board.  I really wanted the students to see just how much they learn about art throughout the school year, so they're keeping tabs of all the vocabulary words, art processes, media and artists they learn about during the lessons on a Word Wall.  I keep blank index cards on or near the board so anytime a student suggests a new word to add to the wall, they can grab it, write the word, decorate it, and staple it up.  So far, they've been very good at pointing out words they can add on! 
Here's pictures of the word walls at each of my schools:
