I have the same situation regarding using things hanging on the wall. I get a lot of decorations from a teachers supply store and use them. They are colorful, heavy duty and can be hung with plastic tack.. No marks on the wall and a lot of dimention can be added. They are certainly reusable. For September I have a
6 ft Scarecrow that will lounge outside of my frame and point towards my calander.
I have a lot of small pieces that I change throughout the fall, but the scarecrow stays until the end of November. I have pumpkins, corn, acorn, leaves, sunflowers, mice, ect... all made from adorable paper cut outs. The residents help
to punch these out so I get an unscheduled group activity in the bargin...
