2 things:
1 - load your brush more. make sure you got enough soap in it to produce as much lather as you desire. twist away on that puck with your wet brush till you get some lather built up and alot of soap up in there. enough soap is always paramount.
2 - use less water in your lather bowl. you can add 4-drops at a time till its producing lather like you want. remember alot of lather is in your brush, you do not need to fill your lather bowl. the point is to make thick, rich, creamy lather. twist and plunge that brush in the bowl and make your lather. your brush should almost suction to the bottom of the bowl when you reach thick lather.. if you got suction and not enough lather for your tastes, add a couple drops of water and start twisting again till you get that suction and re-evaluate the amount of lather. if you see bubbles in your lather its usually becuase of too much water - do more twists/plunges to thicken it up.... and use less water!

ps. if you move to your face and your lather is a tad runny from the water that was on your face, do some twists/plunges on the side of your cheek and that will thicken it up for ya.
