Welcome, Jesse! I am glad you found us!
You have to do some looking, but there are a number of people here that have posted how-to's, in varying detail. Matthias, just a couple of days ago, showed how to weave a pouch, separate from the rest of the sling. I built a similar jig out of a couple of cup hooks and a piece of wood, and I am halfway through weaving one for myself. See his posts in "
How to make a weave sling
". Some of us have detailed how to make slings with leather pouches; Ajlouniboy has some fancy asymmetric ones (his
cobra sling
). Zorrro gave
very detailed instructions
for making a sling from nylon cord and adhesive tape (the stuff from the first-aid kit works well, so does duct tape).
Have fun!
