Virtually the only process shot I took of the entire paper tree building experience. Those cheez-it looking things were corrugated cardboard hole-punched to created loft and height between the pages. I glued dowels to brown paper boxes (in upper right corner of photo) and simply hole-punched and stacked, in varying graduated sizes, pages from an old book. Some of the pieces were more square, while others ended up rectangles. I simply used my eye to determine what the size of the next layer should be and worked my way up to the top.
