Interlocking Double Accordion

I used instructions from Alisa Golden’s website to make this Interlocking Double Accordion book.

The paper came from my stash. I think it is Canson Mi-Tientes. I painted it in a paste paper workshop with Abbie Read a few years ago. It has been rolled up since then, giving the accordion an extra springy quality. I used two strips from the same sheet, one with the painted side up, the other reversed showing the unpainted paper.
