Use an empty egg carton to store golf balls!
For the inside, I put tiny drops of different colored paint in all the different spots.
My son started off using a pint brush and then decided fingerpainting would be more fun!
After it dries, you can store golf balls or anything you’d like inside it.
It also makes a great game for little ones. My 21 month is is very content with trying to toss the balls into one of the holes.
