I've just about got my tarp done! I've attached the first pic...
I'm calling it the Black Cat I think it's appropriate...

Very nice. Watch out and you may give Brian a run for his money now that he has shut down production until he gets thru his first semester.
If I didn't have a MacCat I would definately want one of those. Well heck might be a good idea to post the pattern somewhere.

Nice!
I like the black. What is the size? I also think you should post the pattern.
Very nice! How about some specs?
Great looking tarp. What do you mean "almost done" - it looks finished to me. Unless you're gonna put a batman logo on there or something...
Looks like a catenary ridgeline, too. Did you use your fancy math programs to generate the curves?

IMPOSSIBLE JUST TAKES LONGER
I used the $4/yd. sil from Ed Speer, which worked out great - I got 8 yds., and it turned out to be 5.5' wide. Overall size is then 12' long by 11' wide (before hemming), a little bigger than the MacCat Deluxe.
I wrote my own routine for generating cat curves - the one Youngblood has on Yahoo isn't quite accurate. All six edges are cat cut. I calculated the edge lengths so they'd all be the same - that way I only had to make one cat pattern.
I used 1.9 oz. ripstop from Walmart for the corner reinforcements. The triangles turned out to be 12" wide, 6" high, with the tie-outs opposite the 12" side. Tie-outs are 3/4" nylon webbing that I had sitting around from a pack demo job.
I haven't actually weighed it yet, so I'll have to get that on here when I can. I'll see what I can do about a pattern, too. I'm planning on putting directions up when I get time - I've got two GRE exams coming up in the next week.

Nah, the ridge isn't catenary, I just can't sew straight on a really long seam like that But it worked well, as it turns out; the curve in the seam helps take up some of the slack I think.
"Almost done" means I'm still working out some tension distribution issues with the corner reinforcements. Because the attachment points are narrow, the tension is pulling almost straight into the tarp, and not tightening the edges as much as I'd like. The result is that, while the tarp body is nice and taut, the edges have a little sag in them. I figured out how to fix it today, but it'll take a little more sewing to get it done.

Just let me know when I can place my order to you.
