To frame watercolors, you can follow these tips: Choose a frame that does not stand out more than the work and that matches the style of the watercolor and the place where you are going to place it. You can opt for wooden, metal or plastic frames, according to your preferences. Light wood, white or metallic frames usually look good with modern and colorful watercolors. Dark wood, varnished or matte frames usually look good with classic and sober watercolors. Use a glass or a methacrylate of protection to preserve the watercolor from moisture and ultraviolet rays of light. These can damage and decompose the color of the paint over time. Choose a glass or a methacrylate that does not have reflections to avoid losing the visibility of the work. Use a mat or a foam board to separate the watercolor from the glass or the methacrylate. This will prevent the paint from sticking to the glass and deteriorating. The mat or the foam board also serve to highlight the work and create a depth effect. Choose a color that harmonizes with the watercolor and the frame, without being too flashy or dark. Cut the mat or the foam board to fit the frame and make an opening in the center of the size of the watercolor. Glue the watercolor behind the mat or the foam board with double-sided tape or white glue. Make sure it is well centered and aligned. Place the mat or the foam board with the watercolor glued inside the frame, over the glass or the methacrylate. Close the frame from behind with staples, nails or screws. Place a hook or a wire to hang the picture on the wall.
