Spiral Atlases: playing with The Road to Spring book structure

I like to play with paper. I also like to invent new structures and then stretch, shrink, or change their folding patterns. Below are pictures showing two variations of my book The Road to Spring . The squares that form the base of the structure changed size from 4 inches down to 2 inches instead of staying the same size in the original version. I made a prototype on Wednesday with the squares centered and decreasing by 1/2 inch (see diagram 1). This made a very interesting model and got me thinking about other ways to have a graduated structure (see diagram 2). I hope you like the surprising results as much as I do. Here are my newest creations: Spiral Atlases (thanks Mom for the name).

Enjoy,

Note the notches cut where the squares meet.

Spiral Atlas #2 folded into Turkish map folds in each section.

#1 and #2 with finished Turkish map folded sections.

#1 with Hungarian map fold inserts. 

I used tracing paper hoping the marbling would still show.

#2 with gelatin printed paper inserts.
