Leaf Tower

The leaf tower was one of my favourite assignments of the year, since I managed to make it do something a bit special. The rules were to make a three-dimensional structure out of one sheet of bristol board, with only cuts and folds, and without removing any of the paper. Here’s what I came up with.

The zipper up the back holds the two edges of the sheet together into a circle, and the “windows” on the back are really tensioning struts that hold the front to the back. These struts are then folded on the front side to lock them in place, which along with the fold between them, brings the tower to form an asymmetrical heart shape. I then added the ornamental leaf cut-outs, and bent the leaves slightly outward to make it look as though it was covered with vines.
