I went and bought cheap plastic dinosaurs to spray paint for decoration for Jaxon's birthday party. They turned out perfect!
I used spray paint that was great for plastic and made sure to do 2-3 coats on all the dinosaurs ( I let it dry in-between).
With the bigger dinosaurs I wanted it to be the blue ombré so I sprayed it with the middle blue color first. When It dried, I took the darker blue and sprayed the feet. I did the same with the lighter blue on the head and top of their backs.
With that same spray paint, I re-did my brothers old high chair so Jaxon could use it when we give him his cake.
