The dutch spiral learning project is done. I finished it off into a bracelet.
While looking around at youtube, I discovered that the really nifty spiral earring that I'd seen on Pinterest is also a dutch spiral project, with tapering to make the overal lozenge shape. This could grow into a whole collection of blue-toned spiral whatsits!
