Bale Bags are as versatile as tuct tape. They are good meanwhile stuffing. I’m not sure about them being used in a permanent way… but they sure come in handy as quick wall fill. They can go into a wall quickly while the cob is being made… or over the course of the winter. I used these in my north wall with some light-clay to fill the cracks. It was better than nothing. I wonder if they would work as insulation in a attic?
If nothing else they hold straw all your loose straw and are great to sit on!
