What is a drawing mask?

A drawing mask is a tool or technique used in art and design to protect certain areas of a surface from being painted or drawn on, allowing artists to create clean edges and defined shapes. It can be made from materials like adhesive film, paper, or liquid masking agents that dry to form a barrier. Once the desired application is complete, the mask is removed, revealing the untouched areas underneath. This technique is commonly used in watercolors, airbrushing, and various other mediums.
