In a batch of storm-fall timber that I cleared earlier this year, there were several branches severely stricken with canker, which is probably why they fell in the first place. This little pot is 15cm high x 12cm diameter and is finished in Renaissance wax. I had planned to take the wall thickness down a bit thinner, but with this much bark and canker present, I settled for 6mm and kept safe.
