Small amount of hair, pack, small amount of hair, pack........keep doing this about 50 times and you get a decent tightness. I'm not a pro at dear hair but I found this to work best. Try tying a knot after each bunch, it keeps wraps tight. Also once you get a decent shape with your scissors try taking it out of the vice and using a thin (double sided) razor blade to trim the rest. A little pressure from the sides and you get a nice bend.
