Nice! So true that there are so many resources and videos online and often just getting your hands dirty and learning by doing makes a ton of sense. Certain fundamental knowledge like how to build a foundation and whatnot is the more intimidating stuff it seems.

I've heard of using rice hulls for the top layers of an earthbag dome because they are often very cheap to find and much lighter weight so it's easier to construct with.

Have you also seen the method of earthbag construction using the rolls of potato sack fabric instead of the sandbag material? I can find a video to show you. It's pretty neat!
