Made mine just big enough to get around my hips. Folded the material back and forth then tied knots on the ends. Made an adjustable bridge with a prusik. That way you can shorten the bridge to keep it from falling down when walking, and lengthen it for sitting at hunting height.

Keep in mind that this should ALWAYS be backed up by a rock climbing harness.
I made one just to try it out, and found it to be super comfortable. So comfortable, that if I had tried one before buying my Kestrel, I may not have bought my Kestrel. That said, I have yet to hunt from it because I really like my Kestrel, haha. (One piece with molle loops for dump pouches)
