Wash Tyvek before or after making a tarp? Seems like it would be easier to handle and cut (though noisier) before washing.
I'm not making any seams, so no worries of tape coming loose (though it sounds like nothing can loosen the tape).
I know it shrinks a bit, does it shrink uniformly or oddly? Meaning, if I make my tarp a little bigger on the ridgeline, will the shrinkage pull one way and not the other? I can't make it any wider, because I only have a 7' wide piece.
Experts, weigh in!
Thanks!
