Artists are known for building entire worlds out of thin air.

Some take a two-dimensional approach and others invite a third to the party, letting graphite, clay, and blocks of wood be their creative guides. But some people, like artist Bob Morehead, prefer to inject every single step in their process with a healthy dose of ingenuity.

For Morehead, that starts with his choice of materials. Instead of using wood in the traditional sense, he builds structures out of thousands and thousands of toothpicks.

His most famous project to date is a collection called “Bob’s Toothpick City.”
