A lesson to my future self, a reminder in case my memory cleared its own cache again:
DO NOT use brown marker on white surface to outline shape that needs to be painted with gold (or any) acrylic paint.
Use whatever marker is closest color available. Heck, go outside and buy a marker of the same color (and get some fresh air). The reason is because the brown was a huge pain in the butt to cover up, and managed to dye the area near it orange or pink, depending on the paint. It severely lengthened the painting process.
