This is what I used:
Just some black, orange and white acrylic paint and some glitter spray.
Then I just painted everything free hand so that it would look kid-like and fun. Once the paint was dry, I took it outside and sprayed with the the glitter spray to give it some much needed sparkle!
It was so easy and free because I already had all of the supplies!
The finished project:
Not fancy, but cute, simple and free! We have a lot more plywood, so I may make another one to sit next to this one.
