It was simple. Beforehand, I used duct tape to create shapes all over the wall. When the kids were here, we rotated groups of 4 to paint inside the shapes. The best way to let them access the paint is to put the palettes of paint on a garbage bag on the floor. This is the method I used.
And it worked! It was fun to see the creativity and ideas they came up with, and the kids absolutely loved it! I’ve included before-and-after pictures below. (I waited overnight and then peeled the tape off and it turned out awesome!) Before they left, I had them all write their names on the wall. It was a blast and is a fun way to not only keep kids busy and add color to an otherwise boring basement.
