Step 2: Sandbox
When used indoors I recommend putting your sand box in the middle of a tight weave area rug or carpet remnant. This way you can just lift it up and dump most of the spilled sand back into the box. You can also vacuum the carpet if you want to be extra tidy or take it outside and throw it over a clothesline and beat on it. I prefer carpet rather than vinyl because carpet tends to clean the toddlers' feet and trap the sand whereas vinyl keeps the sand right on the surface to be tracked all over the house.
