Beading and Folding and Sewing, Oh My! An Adventure in the Marvelous Land of Map ColoringThe Famous 4-color Theorem states that four colors are sufficient to color any map on a plane or sphere so that regions sharing a boundary line are different colors. The less well-known Map Coloring Theorem gives a formula for the number of colors needed for a map drawn on a torus with one or more holes. Visualizing such maps is quite difficult. Over the past several years I have been trying to understand maps on these surfaces by constructing models in various media. I have published directions for these models so you can learn how to make your own!You can check out the references here.
