After working on and off for about a month on it, I finally managed to fold the famous (and incredibly awesome) Kawasaki Rose! I wish I could show you the ones that I folded, but I don't possess the technology to do that. If you would like to see some of the roses that another folded (Alex Barber) has folded you can check out this link:
If you can find it in your library, the original diagrams by the original creator are in the book Origami for the Connoisseur . I would reccommend trying that route first.
I had to print my diagrams off the internet. This page looks closer to the original version of the rose, but I don't know if you'll want to print all those photos out. This diagram is the one I used, but it has a couple of small errors near the end, which is one of the reasons it took me so long to figure out. : It seems like nothing but the original diagrams are going to be perfect.
When you figure the rose out Anna, be sure to post it so I can cheer for you too!
