I've been saving plastic grocery bags for about 2 years now. My purpose was to make plarn, but I never got around to it. What's the purpose of saving/recycling/repurposing if you never do anything with it? Sounds a bit like hoarding to me, so this weekend I started sorting bags, cutting strips, and making plarn. There's a greater chance of me finishing the plarn projects once the prep work is done. :-)
No, I don't eat that many eggs. Those cartons have been saved by others and given to me to pass on to my friend M who raises chickens.
