@p Hehe, it's a sketch from 2019 and it's fun because I made my first real work of masonry last week, and if I had to redraw it, I would do it differently. Mortar paste can't be that sticky and solid. I was shocked to see how it was more like mud with sand in it, gluing nothing, and requiring casing for any volumes. So, I totally agree with your observations. 😺
