Happy Valentines Day! :D Well, for this day you would think that I would post a heart model, right? WRONG!!!!! Posting hearts is too mainstream. XD But i'll post one later.....
Going on with the topic, this model is designed by Francesco Guarnieri. You may find the crease pattern at http://www.flickr.com/photos/f_guarnieri/5646264173/in/set-72157622572163478/ and http://guarnieri-origami.blogspot.it/2013/01/fiore-geometrico.html .
Note that you will be following a crease pattern, not some bunch of diagrams. Just try to follow which one are the valley and mountains while staring at the picture of the moel Guarnieri posted on flickr.
If you do the crease pattern right, you will get a nice chubby flower. :)
