Trilobite Harness Pattern?

Hello all! Attached is a picture of a harness I want to make for myself. I am unable to take this one apart so that I can tie a new one. I'm wondering if anyone has a pattern for this kind of harness. I was told the back and thigh portions are a common paracord weave called "trilobite weave". I am wanting to create an all day harness, back brace sling, and seat to go hunting from in the trees. Any info on a possible source for this pattern would be greatly appreciated. Thank you!

EDIT: I was finally able to make my original photo of a low enough quality to post as an attachment to this post. As I originally intended.
