Paint the entire pumpkin with green paint. Let dry for about 30 minutes. You may need a second coat. If so, allow to dry for another 30 minutes. (I painted a blue pumpkin too, so that I could make Sully)
You're going to need a large white circle for the front of your pumpkin. You can go straight for the paint but we like to make one with pencil first, just to make things easier. (I traced washi tape to make this one)
Fill in the circle with white paint.
Using a round sponge brush, place a blue circle inside the white one. I made mine just a little off center.
Use a smaller round sponge brush to paint a black pupil inside the blue eye. Next, use a paint brush to paint the mouth black.
Use white paint to add teeth. Then add a small dot of white to give his pupil a little sparkle.
Add a speck of white to the pupil. Let dry for about 30 minutes and your Mike Wazowski pumpkin is ready for Halloween!
Notes
Use any round household object to trace circles on your pumpkin to make painting it easier. I've used everything from washi tape rolls to shot glasses to make the perfect circle.
If you plan to make a Sully pumpkin as well, paint another pumpkin blue while you wait for Mike to dry...it'll save time later.
