In my final model, I incorporated the idea of the progression of a twig. I purposefully grouped my twigs from the smallest and most fragile to the thickest, however, instead of placing the smaller twigs on the bottom, I placed the larger twigs at the bottom and the smaller twigs towards the top.
Also, working with the number twelve, there are twelve "pockets" for the twigs to lay in and there are three fold to each individual "pocket." There are also two strips of double-sided tape (my binding agent) running across the entire model. This structure definitely incorporates the number twelve and uses its divisors to give a sense of unity to the project as a whole.
