Start by cutting the foam into a circle shape.
Take your time to make a round, smooth circle.
Now, cut a hole in the middle of your circle to make the foam piece look like a donut.
Again, take your time to make sure that your hole is smooth and round.
Paint your donut with light brown acrylic paint.
Keep painting until you have colored the whole donut.
Now, add a layer of acrylic paint to the top of your donut. I have mixed red and white acrylic paint together to make pink.Let it dry. This will take a few hours.You can speed up the drying process by using a hair dryer. Make your frosting using pink puffy paint and add a thick layer to the top of your donut.Let your donut dry overnight or use a hair dryer to speed up the drying process. Now, use a thin paintbrush to add colorful sprinkles to the top of your donut.
Let it dry completely. Your donut squishy is complete!
