Sewing the quick pull loop was super easy once; I just had to think about how to do it. If you know how to sew in a straight line on a sewing machine you two can make your own quick adjust pull loop sling like I did.
Just double it around a slider and put in a lot of stitches in it across. I added some red lines because the sitches were hard to see but the goal was to just put in enoug that you stitch the two pieces together without any gaps forming when you bend it.

Then pull it around and feed it through the other side of the slider like this

Then stitch it closed.

Boom. Now you can loop it through to make a quick adjust pull. I can make a quick video of how the sling works works or I can make it all over again and take better pictures if someone wants a how-to guide. The most expensive part of the sling is the QD swivels at $18 for the pair; the webbing is like 40-50 cents a foot, the sliders are like 55 cents each.
Whole thing weighs 4 oz
