Make your own what now? Yes, this fantastic-looking mobile is a decahedron himmeli. Before you can say that five times fast, Aunt Peaches will have you making one for your own home.
Himmeli are traditional Finnish Christmas ornaments, and Aunt Peaches goes into detail on the history of the art. She decided to adapt the craft for year round, and we found the idea for a mobile terribly inspired. In spite of the fact that you make it with straws, there are lots of ways to tailor it to your style. Use colored straws, or those cute striped straws that come in lots of colors. Or stick with plain white for a thoroughly modern look.
The tutorial is clear and witty, and Aunt Peaches provides great photos. See the whole tutorial at Aunt Peaches.
