Either way, it looks great. Glad you shared this with us.

Thanks! Should be able to get it hung today. Ridgeline reinforcement is Dyneema X, not because it's needed, but because it's cool. The ground tie-outs are HD300 black.

Very interested in the French seam ridgeline & the details on reinforcing/attaching D-rings.
I have done a felled French seam before, but this would be one less step with a whole bunch of material.

Will the Ridgeline be seam sealed in some way? Is the standing part of the French seam to the outside of the tarp or to the inside?

I just played around with the Dyneema X that I received and I can't wait to make a pack out of it. I'm digging the slate blue. Any possibility of more colors?

Cool. Yeah I may try my hand at making some type of simple pack also. I've never done one so it should be fun. We should have Black added in a couple days. Please share the pack when you're done!

I snuck out this morning before going to the shop and got some photos of the MEMBRANE silpoly tarp. Will report back later on some post-build thoughts. I left it out today hoping for rain, so no final weight yet.

Very nice looking tarp. Are you bringing it to HangCon 1 (Annual Florida Hang) in January?

I've always done the standing French seam over the felled seam. I've had good luck without seam sealing when using the standing French seam, but YMMV. I guess working theory is that when you fold over to do the felled seam you're opening the stitch broadside to water, thus making it more likely to come in.

That being said, this is a UL tarp made from the Membrane which is thinner and lighter than everything else I've used. I'll probably seal it for good measure.

...standing part to the outside.

She looks awesome Kyle. I don't think you'll need to seal that French seam. It what I have on mine and it's been through some heavy weather without a bit of problem. Keep it light and enjoy. Hey, weren't you gonna do a giveaway on this tarp?
