Building on the work of Morris, Thorne, and Yurtsever, some particularly simple examples of traversable wormholes are exhibited. These examples are notable both because the analysis is not limited to spherically symmetric cases and because it is possible to in some sense minimize the use of exotic matter. In particular, it is possible for a traveler to traverse such a wormhole without passing through a region of exotic matter. As in previous analyses, the weak-energy condition is violated in these traversable wormholes.
