How to paint a pumpkin
Choose your pumpkin.
A good pumpkin for painting has a smooth, even surface with no bruises, scratches, or blemishes. Pumpkins with light or very light or shallow ribbing will have the smoothest surfaces.
Avoid pumpkins with too many lumps and bumps, or they will be difficult to paint. Look out for any cuts or wormholes that will cause problems, and make sure that the pumpkin is flat enough to sit upright.
