The first coloring book, "The Little Folks' Paint Book" was published in 1879. Crayola introduced the crayon in 1903. And the average American child spends 28 minutes a day coloring and wears down about 730 crayons by the age of 10. Between parents and schools, roughly 2.5 billion crayons are purchased each year.
I can recall vividly my father introducing me to coloring in sheets as a hobby, and now I am doing the same with my child. Never mind how the world changes, our children nowadays love to color in just as much as we did when we were young. Kids love to show off what they can do by using their paints on the coloring sheets you give them.
It can be hard to host a party or other gathering at your home if you don't have lots of activities for the kids to be involved with. You can have a supply of crayons, markers, colored pencils, and even water paints on hand. These will allow them to complete the Spongebob coloring sheets in a creative way.
