My Catalog of Spirals ...so far

I spent a few days last week organizing and making detailed drawings of the spirals I have created based on Tomoko Fuse's in her book Spirals. Here are the results. I have paired the sketches with the samples so you can see how they look folded. I hope you try one or a few. Let me know which one is your favorite. (Mine is #2.)

Enjoy!
1. Basic spiral.

2. My addition to the basic spiral. It makes a leaf shape that I like.

3. This combines two spirals and kind of looks like a ram's head when collapsed.

#3 Open


4. Long skinny trapezoid has more turns than the regular one.


5. This is a different spiral, based on Fuse's Naval shell with modifications by me.

6. Naval shell with a twist.

7 a & b. Variations on collapsing a spiral result in different effects. 
7a is locked in the closed position. 7b opens into a complex corkscrew shape.


8. Note that in this sample the  parallel lines are angles up slightly towards the center fold. This creates the openness in the center of the spiral. (see the picture below)
