In this interactive video lesson [1:05] you can move points, as before, but you can also add as many new points as you'd like. Just click on an interior of an edge to create a new point. And, then, use the mouse to drag the new point wherever you want it. I can make a crude looking hand shaped like this. Use this slider to control how many subdivisions are used to give a smoother result. Using this interactive, make a hand or whatever you'd like. Maybe, a dinosaur, or the outline of Mike Wazowski, or whatever interests you. Be creative!
