I went thru it earlier but I need pics haha. I need visuals on how to do it.https://saddlehunter.com/community/index.php?threads/the-ultimate-ultralight-saddle.2358/
read this whole thread bro
The big thing for the first one I made was figuring out which way the fleece stretched because it stretches a lot in one direction and not much in the other. You will most likely get a few yards(at least I would recommend that) so you can make a few so you don't have to worry about screwing up. There are several ways to tie the ends, I made my first one with a sewn channel but you can tie the ends like a hammock, I think there are a few ways to do it.
Watch this video then just use fleece.

Which way do you prefer the fleece to stretch?
