I painted every side except for the front of the trunk with two coats of the navy blue paint. Even with tape, getting the flag to turn out was extremely difficult and took a lot of time! I used some painter’s tape first, to tape off the area of the flag where the antique white paint would go. After giving it two coats of paint, I filled in the background with the navy blue paint.
I gave it a day or two to properly dry, because I then had to tape over the white part to get the red part of the union jack done. After two coats of red, I waited another day to take the tape off. When I did take the tape off some of my lines were a tiny bit uneven (the paint bled through a little), so I just went over it with a really fine paintbrush by hand to even it all out.
