I put up a plank wall in our basement this summer (using masonite; long story) and had a stack of scraps at the end of it all. I'm a life-long leftover saver ("Oh, I can use this for something") and sometimes use what I save. The boards I saved are about 6x15 inches; the perfect size for something tall and narrow.
I had some sewing patern girls that need a dose of "modern" and a new stack of scrapbook paper. I gave them each a new, bold skirt.
Chevron, monster dots, and numbers. I painted the boards (one with chalkboard paint), layered them with tissue paper and a vintage transfer. I also smudged on some brown ink to give a little more dimension to the images.
Always looking for validation, I showed it to Ellen. She said something like "that's a cute skirt". Nailed it.
