I found a cool old carpenters rule at an estate sale and knew I could do something fun with it. Here's what I came up with. A star wall hanging! It was super easy to make. To keep the points of the star in place, I wound some string around them a few times, tied a knot, and trimmed the string. One of the points of the star has a double layer of ruler, but you can't really tell. I'm definitely going to be on the lookout for more of these types of rulers. You could hang it in other shapes as well, or use for trim on a shelf, picture frame, etc.
