Drawing Gum is a peelable solution used to keep areas of artwork free, for use with ink, watercolour, gouache... It is applied using a brush or pen on the parts of the work to be masked. Colour is applied when the drawing gum is dry. Once the colours are completely dry just rub the gum with your finger or with an eraser to reveal the masked parts.
