1) Make a frothy coffee with the froth evenly spread out and no big bubbles.
2) Place the stencils on top of the cup so that it is resting on top lip of the cup. Do not hold the stencils whilst using it if possible.
2) Fill the cup as close to the top as possible (Less distance between the froth and the stencil makes a better impression)
3) Use a good quality fine powder + fine mesh shaker to get a nice even coating of powder. Depending on your shaker, better results may be given holding the shaker on a angle and moving slowly across the stencil.
