bathing beauties

They look a lot like like old-fashioned bathing caps, don't they? I named them Million Dollar Mermaid (top) and Neptunes Daughter (bottom) as an hommage to Esther Williams movies with the same names - which I haven't seen unfortunately...

The paper used is from an old norwegian childrens book I bought during my stay in Stavanger when I held a workshop there in spring. It's very thick and beautifully discolored, my guess is that it had a high content of wood, but I'm not sure about this.
