...in just nine easy steps.
Step 1: Decide on a 8 ft. by 8 ft. area where you want your sandbox, and shovel out all the lava rock (about a half ton worth).
Step 2: After lava rock is cleared away, dig the area down 6 in.
Step 3: Pickaxe (and wife) may be required to break up rocky soil and tree roots.
Step 4: Measure, cut, and join framing together.
Step 5: Tack landscaping fabric along the bottom of the frame to keep the sand up and the weeds down.
Step 6: Test the payload capacity of your truck by hauling 1.25 tons.
Step 7: Add brace benches while warding off children eager to play in sand.
Step 8: Dump in 1 ton of sand. Be sure to clear the area of children first.
Step 9: Play in sand to see how it feels. Decide you need another half-ton of sand.
