If you go to the paint store as often as I do, and they give you a paint stick every time, you’re bound to have a collection similar to mine. Why chuck them when you can save a reuse them in a great project like this.
If you don’t have paint sticks, look around for other wood scraps that you could cut and use. Anything that comes in strips and is a uniform depth – even old rulers would work. Check out the details of this project at Saved By Love Creations.
