1. If the wood on your frame is treated with a paint or sealer, acrylic paint on its own will bubble and not stick (see above). Don’t worry though— there is a solution!
2. After wiping off the paint with a paper towel and reevaluating my color choice, I sprayed the frame with a coat of white primer. After it dried, I was able to apply the acrylic paint without any issues.
3. Tape of the sections of the frame you’d like to paint gold. A few layers of paper will help cover the parts of the frame you’d like to remain untouched.
