Pastel on Canvas
To obtain a true pastel effect, it's especially important to choose a right surface. Generally, pastel artists use a textured paper. With the AKVIS Pastel program you can put your painting to any surface: sanded paper, MDF board, brick wall, and others.
In the Decoration group switch to the Canvas tab to choose and adjust a texture for your artwork. Enable the Use Canvas check-box.
Hint: You can drag the Canvas/Frame/Text tabs to change the order of the application of the decoration effects.
