Leaf Bag Stiffener
Forget adding cardboard stiffeners to a leaf bag.
Paper Bag Trick
The problem with paper leaf bags is that when they’re empty, they collapse just as you start to put leaves in them. You can buy those fancy cardboard and plastic bag stiffeners, but why bother? I just roll the tops of the bags inward. This holds the top wide open while I dump in the leaves and other lawn debris. — Greg Reinhard
