We're always looking for class lists to use for record keeping, or to keep track of who has brought in what for trips etc. I use file folders to give my lists a place to hang in my room. I like having these out of my cabinet so that I can grab them easily or ask a volunteer to grab one without having to root through my filing system.
Simply use a file folder and tape up the sides to make it into a pouch. Put a label on it (everything has to have a label! ha ha) and use double sided carpet tape to tape it to the wall. Those cinder block walls don't like anything hanging on them, but carpet tape seems to do the trick.
Here's the finished product!
