I'm on an AIGA Center For Sustainable Design (CFSD) committee so have become conscious of my consumption and waste.
I drink a lot of water, travel a lot and spend a lot of time in New Orleans where the water is of dubious potability. We have excellent well water at home so all I needed was something in which to carry it. I researched plastics of all kind and got real scared by most of them. I found a perfect and beautiful stainless steel canteen bought by the U.S. Army but it retails to civilians for $90.00. Plus, the washer on the plug was made from one of those plastics I didn't like.
I noticed a glass, wine-size beer bottle with a re-usable stopper in our cupboard, someone had give us a holiday gift of fragrant viniger in it the year before. So, I started to haul it around. But the exposed glass frightened me and I wanted it protect.
We recycle those those nasty little shopping bags and had collected many.
It dawned on me that I could make an insulating bottle container of my own:
All you need is the bags, a pair of scissors, a large crochet hook ($0.95) and time.
