Custom Diamond Painting is a craft hobby that involves creating a unique piece of art by placing small resin "diamonds" onto a canvas with a printed design. The process involves using a special pen tool to pick up and place the diamonds onto the corresponding symbols on the canvas. Custom Diamond Painting allows individuals to create their own designs, pictures, or photos by converting them into a canvas with symbols that correspond to different colors of diamonds. The end result is a sparkling, colorful, and textured artwork that can be displayed or gifted.
