How to build an accurate model of birds to scale?
I have to build a model of a bird, specifically Tanagers. The model must be flying, precision scale (11.5in) specifies the length (about 6-7in) and must have an attachment to hang ceiling. I know what this project has nothing to do with the preparation of an environment AP test? I do not know where to start on this project. It can be made with clay, as it must be light. And if I had to start with a wire or paper mache, then how could I start he sculpted for a specific model? Thank you in advance!
Try making a clay sculpture and using it as a basis for a paper mache. Good luck.
