I made this over winter break, following a pattern from Miyuki Kawamura's "Polyhedron Origami for Beginners" (although I inverted it to give it texture; normally each face would be smooth, but I liked how the 'internal' folds looked).
It's a stellated dodecahedron (aka dodecahedral star) made from 30 7.2x7.2cm units of construction paper. There is a little bit of tape holding the modules together. As you can kind of see from the picture, it has three colors, none of which touches itself along a side.
It was my first try folding origami from construction paper -- the heavier weight makes creases softer -- but I think it turned out okay. Since I took pictures during construction, I may make a tutorial if there's interest.
