this is glorious headchange! love the self-contained, anti-loss aspect of this!! one small adjustment i recommend is the Alpine Butterfly Loop as the knot for the loop at about 12" because it bears the load more evenly on the cordage, lessening the strain it takes. doesn't really matter much for a tarp i guess, but im all about using the best knots, techniques, methods, and so forth. think i'll make mine short so that i can add appropriate cordage for the locale's tie-off availability.
