Using the left-overs of the black sugar paper (245x245mm), the songbird was "born". This design is in Robert J Lang's Origami Design Secrets, in the grafting section. As you can see, although not very clear, there were toes "added" to the feet of the bird. This will give the model a more realistic look and feel.
Most of the design will start of with a simple base and look. By applying techniques like grafting, tiling, circle packing and others, the design will become more complex and more life-like.
Some one from the internet asked for help on step 19 to 22, so I made a video on how to fold these steps. It was fun to capture the video from a webcam as you have to make sure the folds can be seen clearly while you are working on the steps.
