Sometimes the cheap solution is the easy one. Use clamp hangers and place some rubber between the clamps. The rubber will hold the paper without ripping by having a small area between the top and the bottom that cant be pulled through. The paper will not rip but it may crumple after a few years. You just need to attach the hangers to each other by welding a rod to them and your wife will need to unlatch them one by one. Still it would work great for little $.
