As much as we wanted to do a fully Natural Built structure, we bought an old house for a crazy good deal and remodeled it. We were not going to throw drywall out that wasn't necessary and towards the end of our remodel we had a baby on the way and needed to hurry up and get in the house. Even though I wouldn't have the cob walls I wanted I did opt to have natural wall finishes. Here's a video of two we made a few years ago about our experiments with limewash, Milkpaints, and clay paints from clay we dug up in the yard I must say the clay paint is a little dark but it definitely was the easiest and cheapest option.
Just a few videos there old but I haven't posted a while, and thought it would be fun to participate in a pollinator scavenger hunt. Happy building folks
