Where will it go?
If you’re framing works on paper or photography for a gallery show, simplicity, quality, and proportion are important. If it’s framing for your home or office, you can decide based on your personal taste. Bold, classic, or simple would all work.
A good general rule: Always make sure your frame supports the art, and doesn’t upstage it. That is, it should enhance the way it looks, with consideration given to how it will look in the room. If your drapes are blue and end tables are silver metal, a blue mat and silver metal frame isn’t necessarily the best framing combination.
Consider scale, art style and matting
The size of your artwork and the style of your artwork have a lot to do with how you frame. Good matting can enhance your look considerably.
Your frame: Which one is right?
No matter your artwork or framing budget, you want a frame and a color that will make your art the focal point of a wall or room, or simply pulls out a specific color in the art. Choosing the right style, color, scale, and texture is vitally important.
