This is a real pretty design of a Rose and doesn’t look complex as it looks. I would rate it as lower Intermediate and origamists who have some experience with different folds such as ‘sinks’, etc will be able to fold this quite easily.
What you need:
The paper I have used is 6” single sided, solid colored origami paper. You can also use pretty wrapping paper or any other paper cut down to an appropriate size.
You might also consider a larger sized paper, say 8” or so, as this would give more “bulk’ to the rose petals; therefore making the rose as a fully bloomed flower.
Avoid using thick paper as this will make it difficult to fold and cause the paper to break / tear.
You can use both single sided colored paper, as well as double sided colored paper. Either way, only one side of the paper is actually shown on the outside, and this is what matters the most.
How to fold the ‘Kawasaki’ Rose:
I found this very helpful video on YouTube.com, which explains in detail the various creases, involved. It is however, divided into 3 parts, and of 2 minutes each!
