Professional framing can start at 100’s of dollars but quickly become more expensive as you customize your frame with decorative mat. When searching for a frame, I look at the overall dimensions of the artwork, e.g. the size of the paper and see if it will fit in a “store-bought” frame. Most frames come with a mat. The picture opening is a standard size 8 x 10 inches, 5 x 7 inches, etc. To properly present your gift of art, ask your local framer to cut a piece of mat board that fits within the store-bought frame, but has a window that works best with your work of art.
The “store-bought” frames are not recommended for original art. Sissy & Roché will dapple in simple framing of my work but Framing by Anna in Kingsville would be a good place to start for professional, archival framing.
