Hi, I just saw the classroom that I'll be teaching in next year and found out that the walls are not the "bulletin board" type that you can put pins in. I had planned on covering the walls with different fabrics and borders to create my bulletin boards, but now I'm not sure what to do. I don't really want to use just the small bulletin boards. I like to use the complete walls for color and displays. Maybe I can put up fabrics and then use tacky stuff to put the displays up, or put cork up on the walls first. Any suggestions????
