Assuming your current brush is still serviceable, I recommend that you practice with it, a lot. Make lather in the palm of your hand or in a bowl several times a day. Make the lather as wet as you can.....then make lather as dry as you can. Make lather by loading up the brush with soap as much as possible. Make lather loading up the brush as little as possible. Try making a good lather in less than 90 seconds, then make a good lather with no time limit. Watch videos on lather making. Somewhere in the middle of this hodge podge, you will learn to make a great lather.
