Latex Wedges - These are great for stencilling. When you want to create a multi coloured stencil, a brush can often be too hard to maipulate into specific areas. Latex wedges are perfect to give you more control for detailed work.
Dip into the paint, then remove excess on a paper towel, the same as you would when using a stencil brush. Do not overload the sponge. Less is more. Tap lightly into the areas you want coloured. Apply a second layer when dry to get the depth of colour you want.
