I'm looking for the large size (6' x 8') polycryo ground cloth. Let me know if you're willing to part with an unused single sheet or pack.

If you don't find one, two mediums joined with two sided tape might work?

Why don't you check with Gossamer Gear, perhaps they have some of the large sizes left over?

Gossamer Gear no longer has the large size. I was hoping that someone might have an unused one stashed in their closet.

These groundsheets are cut from shrink to fit window plastic (the kind applied to the inside of the window with double-stick tape) which is why they will shrink when exposed to high heat (like the inside of a car sitting in the sun). It can be found at well stocked hardware stores (like "Hardwick's" in Seattle) in 84" wide bulk rolls (as well as smaller precut sizes). I've used both Gossamer Gear Polycryo and the stuff from the hardware store and there is no difference that I can detect except of course I didn't have to cut the GG sheet to size.

You mean like this?

That looks to be the right stuff, although the brand I'm familiar with is 'Frost King', who offers 84" wide bulk rolls.

Nice info Linsey, I'm going to have to remember that.

Thanks!
