This dog is special in that it has a scarf around the neck from a second piece of paper, so you could say it's a model from two pieces. There are some judgement folds for the shaping, and it has several closed sinks and 3D steps.
For the dog:
- One square, 35cm (~14"), single-color
- strong paper, tant or canson should be fine
- the ones in the picture are folded from danshi, but that may be too difficult for a first fold
For the scarf:
- One square, 15cm (~6")
- single or duo colored kami is fine
