Small Scale Military Headquarters

I am trying to put an Afghanistan diorama together. I am trying to find something that would work for a hesco barrier. I checked shapeways But didn’t see anything that would work. Anybody have any ideas?

Looking at pictures the texture of the bags look like paper towels .

It is possible to get the wire mesh using patio screen .

Typical screen has 1/16 inch grid holes .

To scale you need 1/4 grid holes.

If you can get the right kind of screen you can pull out the screen threads producing the 1/4 inch grid.

Here's a pic for reference....



....because I had no idea what you guys were talking about.
