yes, knowing i would have difficulty parting with my backtack bag, i made myself another at the same time...
fabric outer sourced from here but also available from here (although i can't see the same colourway at the moment).
fabric lining sourced from here (so wishing i had another metre or two of this but it appears to be discontinued. too sad.)
seatbelt webbing and strap components sourced from here (these guys are finally online - hooray! go to online catalogue - webbing - seatbelt and plastic fittings - slide and loop).
and dark, dark denim from stash. (and i wish i had another 10m of it for pants. and a skirt. or three.)
