Plastic table covers for Bulletin Boards. They are bright year to year without fading, and it saves some trees. And cheaper than fabric! I don't know if you have any bulletin boards Lane but this is neat.
I love colorful displays, so this crayon classroom door display "Get Ready for a COLORFUL YEAR! OUR NEW PACK" is an idea I'd love to use. This idea would also look great as a Back to School bulletin board display. Put all the kids names up to be a crayon.
