Two HH expedition asym stock tarps, one HH Poly Hex. Iv'e wanted to add panels to close the HEX, to close the ends that is, like the WB SuperFly.
Im thinking of using those two tarps and maybe cut them (resulting in 4 pieces) and sew them as small panels to the ends (two for each end). Or maybe i could work arround them to just add two big panels (one at each end).

So, how would you fellows proceed with this, obviously ignoring the resulting weight fo the tarp since the two stock tarp are also PU coated Poly?

I always carry the small tarp and the hex, adding another small tarp to the weight i dnt care, so i just figured i could sew them all togheter the get one big nice tarp (ii little heavy , though).
