We started by painting one side our our boards cream. We literally coated that thing like 5 times. Once it was dry, we added our "you are my sunshine" vinyl. If you decide to do this project, you need to make sure the vinyl is completely down and sealed because you don't want the paint to creep under. Once you've reinforced the vinyl, paint over the top of the vinyl. We painted each layer relatively light. We painted maybe 3-4 coats, painting the last coat pretty heavily.
Now... if only the sunshine will start sticking around!!!!!
