I'm no expert & I've seen it done various ways. For me, they key is making them tight. In fact, the heavier I go, the tighter I tend to wrap. As far as technique, I wrap a couple of times below the knee, then start crossing diagonally behind and in front of the knee, ending with a couple of wraps above the knee. When I'm done, the wraps typically make an X on either side of my kneecap. For me, this seems to work better than just going around and around until you run out of wrap.
