Instructions
Measure from edge to edge of the sandbox both ways and add an extra 8 inches to each side so there is a total of 16 inches extra for each of the two tarp dimensions. This will allow a 6 inch overlap on each side including a finished 2-inch sewn hem.
Order the canvas based on this total "cut size" not the finished size. Have a tailor with a heavy-duty sewing machine sew a 2-inch hem all the way around, or do it yourself if you have the equipment.
Punch holes in the four corners within the 2-inch hem space using a hole punch from a heavy-duty grommet kit. Cut away any remaining material from the circles with a mat knife and small scissors.
Slip the top and bottom grommet pieces into the holes and place on a flat, hard surface. Hammer them together with the appropriate grommet-set sealing tool.
Drill 1/8 inch pilot holes with an electric drill into the outside face of each corner of the sandbox. The holes should be 1 1/2 inches from the corner edge laterally and 6 inches down from the top edge. Screw in a 2-inch long cup hook, also known as C-hook, at each corner.
Place a large bucket upside down in the center of the sandbox or some other object that will help to keep rain from collecting there. Stretch bungee chords or bungee balls from the tarp corners to the C-hooks beginning at one corner and working your way around until all the corners are secured.
