Starting on my winter tarp today using silnylon. First off, working with 9 yards inside a house is a bugger. I never guessed how slick this stuff is while tring to pin it to make my ridgeline. Am I missing something with pinning it or is their an easier way to prep it first? It almost seems like jumbo paper clips or clothes pins could simplify things? Any tricks,out there to help an old goat out?
