Tarp ridge line material name?

[Taildragger]

I am gathering parts to make a tarp. I need the material that joins two pieces of of fabric that forms the ridgeline similar to the ridgeline on a Warbonnet Superfly. Does anyone know what that material is called?

Thanks for any help.

I believe its just grosgrain, not positive?

Yep it's grosgrain.

I thought the reinforced pull outs were grosgrain. The ridgeline on my Superfly looks more like a thin fabric with edges treated so it doesn't ravel.

It's not as easy to decide which kind of grosgrain is best for this purpose. I used this nylon twill webbing and made very good experience whith it:

It is 0.54oz/yard material, easy to fold and strong enough. I will use it again and the same 3/4" material for all my tarp tie-outs with 20mm Beastee Dees on my next silpoly tarp. I will make a double folded seam (no french seam) below the twill webbing this time.

It's not grosgrain.

It's single sided polyester satin ribbon, with the satin side folded in, so the matte "back" of the ribbon is showing.

I've used offrey brand from sewing/craft stores with no problems for years now.



Twill tape will work too. Don't get acetate though. Nylon or polyester.

I personally think you'd be better off with a flat felled seam than a bound seam, little harder to make probably but strong and flat (as the name would imply )

Flat felled seam is also easy to sew and also strong, but with two drawbacks:
a) you have to seal your seam and most likely not only once
b) you can never have a very high ridgeline tension

The second aspect can be very important under extreme windy conditions.
