RE: Making bag targets.... Any Suggestions
I stuffed an old duffel bag with old clothes/blankets/towels/rags. It works beautifully. The duffel bag was one of those big rectangular ones, with the cardboard square in the bottom. It stays in nice shape. I wedged cardboard around the sides to help it keep its shape, so it stands on its end without needing to be propped up.
Cost: $0.
The front of the bag keeps getting ripped open from my muzzy practice blades, but that's nothing a few rows of duct tape won't fix.
