The crease patterns depicted are from folded flowers: 

Tulip, Lily, Kusudama, Bellflower, and Rose. 

When folded, the folder coated their hands in charcoal 

powder, leaving a trace of themselves in the flowers.

In a way this is a bouqet. 

In a way this is an invitation to fold a flower for someone you love. 

In a way this is love. 

“Origami crease patterns serve many purposes: 

To the designer, they provide a structural representation of the artwork. 

To a folder, they can provide signposts on the way to a fold. 

To the everyday viewer, they provide an alternate way of looking at the folded subject:

in a crease pattern, you can see everything that is hidden in the folded work.”
