Hi everyone!
I got interested in an (ultra)lightweight camping setup a little while ago and since I love DIY, I plan to try to make myself some gear. Tarp-wise, the Ogee design seems like a very nice compromise between weight and coverage, which I will be able to use in all seasons. However, I'd appreciate it if some of you pros could give me some feedback on the (very slightly) modified design I have in mind.
Below is the design, the original dimensions I got from a post by cwciwatch (link). I've also attached a PDF with the design. In case the image is not readable, the PDF is a vector, so zoom away . It's to scale by the way, so anyone interested in making one, scale it up 10x and you'll get the same size as the marked dimensions.

The next few sentences are going to be hard to follow without having at least a look at the design . Note that the apex/maximum/... (green dots in drawing) of the big catenary cut is not at the same location as the "hex" tie-out point (the one you would use with the triangles flapped up). This is not possible if a continuous catenary curve is required from the central triangular tie-out to the door tie-out. An alternative would be to split this long catenary cut into two shorter ones, however, in that case the two catenaries will not be tangential at the "hex" tie-out point. I guess that most of the time either the triangle tie-outs or the "hex" tie-outs will be used, not both at once. Are the catenary cuts as they are right now going to be a problem? Would it be better to split them up? Is this such a tiny detail that it won't matter one bit, because my first-time hemming won't be nice anyway ?
A second (even tinier) modification is to add catenary cuts to the inside of the doors (lightest blue in the design). I'm guessing this is probably a bad idea, since it will make closing the doors completely harder. Correct?
Any other ideas for possible improvement? Did I overlook another/better design for my first tarp?
Edit: Updated attached PDF to newest version.
