The recommended materials for these assignments also presented challenges. All of the examples from previous years were made from impractical shapes that were easy to construct as a model, but posed no concrete use otherwise. The issues of accessibility were a constant concern of mine, as was sustainability. This prevented me from making a cardboard or construction paper assembly of colorful shapes. All cardboard used in the project were found on campus. Using it in the most effective way to create strenghts, and preserve construction material, was difficult to plan, but simpler in the end.
