Can you answer gumbledim’s question about Luggage?:

I can’t afford a heavy swinging bag by any means, but I’ve been trying to find something that will work that I can just put together on my own. I’ve tried a pillowcase on the suggestion of a martial artist friend of mine, but it wound up ripping the fabric, so I need something more durable. So will a duffel bag work? If not, any other suggestions? Thanks.
