Whomever made the sadals on the right has my admiration! Waste not want not. One tossed away plastic liter bottle and some discarded cloth can save a life by allowing foot flight over stony ground don’tchaknow! ... And you might be surprised how many folks use the cottage cheese containers and other plastic receptacles which bring and preserve foods. [My favs are the plastic V8 bottles with the label removed ... make great sidewalk lanterns with a votive candle inside, after you do a bit of creative knife work.
