We use a lovely canvas paper that gives our prints great texture and makes them very resistant to the trials of shipping.
All our prints fit standard US frame sizing with measurements in inches. The sizes in the drop-down menu indicate the size opening that the image will fit. There is a white margin in addition to these measurements to help stabilize the print behind a mat. If you don't intend to use a mat, the margin is easily removed. A dotted line indicator is included to help make image placement easy.
Prints do not include a mat or frame.
