For the Zoom Q&A on February 15 at 2 p.m. I will ask — why does this button have concnetric circles of different colors, yet it feels smooth, with everything on the same plane? It’s a thin button, but could thinner layers have been inserted? Sew through with etching, steels, and possible inlay?
For the Zoom Q&A on shell, I am asking — is this a shell button? What material surrounds the shell? Composition? Horn? So is it Composition with inlay pearl and inlay mirrors? (What are the shiny circles called, and what are they called when they are not shiny but black?
