Triangle...

I began to concentrate on the triangle. I made a smaller, more manageable, triangle to see how it could be used to make part of the structure to represent the Modu_gram collection.

Keeping in mind that I wanted the Play with Shapes collection to be partly represented by a square, and that I want each section within the pop up shop to flow into each other, a square within this model seemed to be a perfect place to begin the merging of shapes.
