Well, I don't know if it's of much use to you, but when I first formed my original Filthy Crew , I went to a fabric store, and bought Yards of inexpensive scarlet cotton gauze-like fabric, then used a knife to slash the ends into swathes for sashes. We simply knotted the ends, and wrapped the sashes around our waists, then put our belts over the sashes. That way you've got a double security for boarding implements, money bags, flasks, tankards, jenny-be-safes, etc. Worked like a charm, and it's become a ragged, if noble-ish, mark of our affiliation.
