REI Blue Poly Tarp 14'x12'
Here's what other sites are saying:
The basic 14 x 12 ft. tarp is great for around camp, a tent fly, a boat cover, storage cover or a woodpile cover. Aluminum eyelets every 3 ft. provide attachment points for rigging it up as a canopy or for securing it down. All sides are heat sealed for greater durability; edges are reinforced with polyethylene rope in hem. Woven, laminated polyethylene is tough, waterproof and mildew- and rot-resistant.
