Query: Sandbag

The sandbag served its purpose. However, what you can't tell from the picture or description is that there is an opening at the top of the bag with no way to close it. I assumed there would be a zipper or something similar to keep the sand in! I ended up doubling the fabric over and using a safety pin. Not ideal, but we made it work. If I would have known, I would have paid a little more for one that closed up.
