I created a model and need to know how to connect the vertices together to make all the faces show. Anyone have any idea how to do that? Maybe a link to a tutorial?

In edit mode, select your two vertices and press the "F" key. This will connect them with an edge. To make a face, highlight 3 vertices (for triangular) or 4 vertices and press the"F" key. You can not connect more than four vertices at a time.
