In no time patterns come to life with realistic depth, dimension and textures. With the design preprinted onto the board, there is no need to worry about subject. The 8-inch by 10-inch format works beautifully in standard frames when completed. Engraving Art are ideal for children, adults and everyone between. And, because there's no paint and brushes, they make the ideal travel art project.
