This is great for mark making and lovely outdoor play on a hot day! So simple, no clean up! Fill up a trug with water, add mops, brushes, brooms, sponges, spray bottles. Sit back while your children play. Dipping their tools in and making marks all over the garden/pavement/shed. :)
Tree Stump Walkway I love this idea. It would look so nice in many places on my property. I saw something like this in Germany when I was there. They had it done in the aisle of their carriage house. Very cool!
