It is best to start laying bags starting at the corners and doorways and work toward the center of the wall. And when you get to the center, you’ll probably have these small spaces left. I call these custom bags. I’m going to demonstrate how to fill this gap with a small bag or custom bag. I just estimate about how much soil will fit here. Remember it will compress quite a bit. Just fold the bag over. And then just tamp it into the opening.
I’ve recently published six new YouTube videos on various natural building topics on my Earthbag Natural Building channel.
