Glad you’re finding the site informative. If you want to buy a ready-to-go sandbag, you can get one from http://www.ironmind.com . I haven’t used one, but Ironmind has an excellent reputation for quality. They’re pretty expensive though.

Personally, I just went to Academy (a sporting goods store) and bought a good duffel bag. You’ll want one that is fairly heavy (mine’s nylon). Mine was $10 (a few years ago). They also had some cheaper, thinner nylon bags that can work as inner bags. And even with them, I put the sand in small plastic trash bags.

So, I put the sand in several plastic bags, then those inside a few thin nylon bags, then put them inside the main heavy nylon bag. This gives you a few layers of protection to keep the sand from spilling out. It also allows you to adjust the weight of the main bag. Say you make five thin inner bags at 20 pounds each; you can use four for 80 pounds or all five for 100 pounds, etc. Or, even if you just have one or two thin inner bags, you can still adjust the weight by adding/removing the plastic bags. One other tip: remove the air from the plastic bags before tying them closed.

The way I built mine might be overkill, but it works for me.

For sand, you can just get play sand from a home improvement store.

Good luck! I’ll email you as well.

I want to find sandbags but can’t. Where do you get them? I checked the farm supply store, nothing there.

I’d appreciate a response by email, if you don’t mind, so I’m sure not to miss it. I surf so many blogs. But certainly I’ve bookmarked you.

Thanks!
