A really good blog post that shows step-by-step photos of how to make your own spinning wheel.
The white surface is dry-erase vinyl that comes in rolls. That's a great idea because it allows you to change how many sections you want on the spinner, and write directly on the spinner.
***Only thing I would change in the DIY instructions:
Use wooden dowel pegs instead of nails on the spinning wheel. Easier on hands and safer when spinning.
