i always leave my soaps that come in a bowl or tub in that bowl or tub. the soaps that come plain as a puck i put into a plastic or glass small dish the same diameter as the soap.

little hot water, your wet brush and about 15 or so turns on the soap and your brush is now loaded with soap.

move to your small bowl, coffee mug, whatever item you are using to create lather and add a touch of hot water and spin away in that dish to make your fantastic lather. thats my style.

*******
1 bowl to hold the soap permenantly which i use to load the brush with some spins
1 bowl in which to create lather, bit of hot water and your loaded brush
