Yee, if you want a light, cheap tarp, try Harbor Freight. I just bought 3 7x9 tarps for covering wood at the campsite, rain covers, etc. They were on coupon for $1.99 each. The quality if fair and if you don't plan to carry them on your back they are great. I often use one when cleaning the roof, then drag the loaded tarp across the (not grass :-) yard and have not had one tear or abrade significantly yet.

Respectfully,
