Maybe this is the idea you are looking for Carolyn! You can change it up for any season!
Think this might be the post you are looking for Carolyn
I think the project I did is what you are looking for: http://celebrateanddecorate.com/fall-decorating-idea-diy/
I would definitely start with a picture frame and work off that. You can pick them up at a thrift store. You may luck out and find decorations there or at your local dollar store. Good luck!
