When we lived in a large city and my son worked at a major grocery distribution centre, he would collect and bring home all the plastic mesh bags that onions came in. Each bag would have held about 20 lbs of onions and normally would have gone into the garbage at the end of his shift. I took them apart at the seams and then stitched them to each other like a big ugly patchwork quilt, using scraps of ribbon or old shoe laces, string or anything I had lying around. We had a garden out of town at the time which was continually being visited by deer and other animals. My goal was to create a cover cloth big enough to protect the entire garden. It worked well because the holes were large enough to not block any rain or sunlight but were small enough to keep out deer or other critters that wanted to eat my veggies. It was also brightly coloured and made of plastic which I imagine felt bad in their mouths if they tried to bite through it. Used it for two years until it was blown away one day during a really bad storm.
