So, I used plain white matt emulsion paint for my base coat.
I did not think it would work at first, but it did. You simply need to apply several coats, especially if you are using a white base. This is frustrating, but worth it and it does give you a good base to start your design.
Turn the pot upside down, and work on the main section of it first before you paint the edging. Make sure you work with the grain of the pot as this will avoid missing sections and streaks.
Remember to paint about 2 inches inside of the pot, as you will want to paint over this when you create your final design.
