The bird base rose, created by James Sakoda, is an easy rose to make, comparatively speaking :) Turns out quite well. I think the rose looks best when the paper size is around 4-5 inches. I first tried it with a 6 inch paper and it turned out a bit too big.
As the name says, the model starts with a bird base, which is the starting point for folding origami birds such as the crane and the flapping bird. The bird base rose is an extension of the bird base.
