I usually do my grocery shopping at Ralphs and I noticed how lately they changed their plastic shopping bags to very thin ones that they are not very strong.
I think it's because of the law that is trying to lower the use of plastic bags.
What an excellent idea! So, I would like to help with the environment and that's how I designed this huge market bag. I had some leftover very strong cotton so, I started to crochet my bag. I took me quite some time to finish (2-3 days), but I was worth it!
