I've made a lot of reusable bags for my daughter. I made them from feed bags (the ones made from plastic weave....not the paper ones). They hold up really, really well. Some I've made with web handles & others I made with the bag "fabric". They are very, very strong. I haven't made any for myself but have lots of empty feed bags waiting on me to make.
Here's the instructions that I generally use for mine.
