I also don't know how I am going to do the side pull outs because I had a lot of trouble lining up the webbing when it was on the edge of the tarp, which is a lot easier than when I try to do it in the middle of the tarp.....
No, you're not crazy: an asym tarp does sag more than a seamed tarp; the seam adds a bit of tensional strength where the tarp needs it.
The needle holes...well, keep an eye on them (I sure am with my new tarp!). I'd recommend putting some seam sealer over 'em anyway: not only will it keep water from coming through, but the silicone (or polyurethane, in your case) should help with adding a bit of strength just where the tarp needs it.
Are you intending to put the webbing all the way around the tarp to create the pull-outs? If not, just sew to one side and then sew the reinforcement on the other side using the needle holes as a guide. Easy-peasy.
Oh, and all of that looks really
nice...much nicer than my first efforts, that's for sure! I look forward to seeing what you have in store next!
