A small collection of origami hearts (which will probably be used as bookmarks around here -- you can see how they interlock). Pattern is from Origami for the First time by Soonboke Smith.
Largest heart is made from an 8.5" square and measures approximately 4.25". Then they go down to 6" paper for a 3" heart; 4" paper for a 2" heart; and 2" paper for a 1" heart. The small one is the smallest thing I've made and good practice for some origami crane earrings I'm considering.
