We’ve been plastic welding the tarp seams like the one bellow with a modified heat gun.
In order to look like this:
Can you spot the weld line?
Welding loops on the inside tarp
So we can pass a rope through. Soon ut will serve to sinch tight the exterior wall canvas
And then cutting, gathering- pulling taught and welding the areas that are not lying flat.
Gotta love the implied nudity.
