Things You'll Need
Instructions
Lay a heavy duty 6-foot-by-8-foot plastic tarp on the table.
Arrange a batting such as a bed comforter that is not used any more on top of the tarp.
Trim the batting with shears to the size of the tarp. The batting should cover just the inside of the tarp, leaving the grommets on each side free. A comforter that has been cut may need stitching up along the sides if it has filling inside.
Lay a matching tarp on top of the batten, making a sandwich of the materials.
Backstitch around the edges of the mat, sealing the two tarps together with the batten between them.
