I love the idea of upcycleing (or taking something of little or no value and turning it into something of more value). Here is one of my favorite projects. I think that it expresses the true spirit of upcycling. I took several plastic bags and made plarn (plastic yarn). This project is simple to knit but knitting with plastic does go much slower than knitting with yarn.
There is a full dishwasher soap bottle in the bag. The bag is strong enough to hold cans as well. I think that I will try to stick to fruits, veggies and items that are lighter as I don’t want to remake this unless I sell some. It would be fun to create one using colored plastic bags.
