I seen a guy about 10yrs ago at denton hill and he made a back quiver out of cowboy boots,,, said he went to a couple pawn shops and bought two old pairs of boots for cheap and sewed the top parts together like a tube and just stuffed the bottom and closed it,, the very top was the actual top of one of the boots. it looked cool and I never seen another one like it,,, just an idea.
I guess engineer and harness boots would work too. the jean leg someone mentioned sounds cool, maybe leather jacket arms cut off too.
