I just made a handful of large rough totes for my underhouse excavation project. These will be used for haulin' crawlspace dirt.
They're made outta 22oz vinyl-coated polyester. A lot of bagmakers use this as their liner material, but I much prefer acrylic-coated polyester, as it doesn't stink as much and is easier to work with (isn't as sticky). But VCP fit the bill for this project, given its stiffness, toughness and relative cheapness. The grey handles are folded seat belt webbing. Bottom dump handles are regular ol' one-inch nylon webbing.
