Sorry this is late posting today. Apparently the postal service of another country, that shall remain nameless, has delivered a package of my jewelry to the wrong address. I've spent the morning sorting out the mess. Onto more interesting things...I stumbled upon this low tech, minimal tool way to size polymer rings. I've seen it suggested that you form a ring around some sort of tube like a piece copper pipe or some other bit of hardware. Problem is, this limits the size to whatever tubes…
