Origami Flowers: Primroses

Spring is almost here. Let's celebrate it by folding some colorful origami flowers!

The Primroses were designed by Benjamin Coleman. The instructions can be found in his book Origami Bonsai.
The vase is a variation of a traditional kusudama piece (video instructions can be found here).
I folded the flowers with 3" (75 mm) squares of TANT paper, and the vase with a 6" (150 mm) square of scrapbook paper.
