The Big Pot grew by another couple of inches just now.....
I'm not sure that it might be going out a little too much. That wont be difficult to change, just a little cut and shut!
The next question is how tall. I think possibly a hand-span taller, then add the "roof" which will be slab built. I could do a slate roof, but that would start to get complicated....the next one, perhaps?
I've wrapped the base so that it doesn't get too dry to cut and model/carve, and the top inch to keep that damp ready to add more coils.
