Update: e-mailed a museum! took the ratchet strap for my Tramper out to the garage, where it lives! retrieved the last pack of wool! took all of the packaging materials AND THE COMPOST BIN to the allotment! and fed the compost bin, dropped off the wool, and distributed the cardboard and paper packaging. Which was more than I intended to do, and took me less than 45 minutes. Thank you collectively for your unwitting but very helpful support. \o/
