I thought you might be interested to know how I go about.
Here are five key questions and some pictures to visualize what I am talking about.
1. Do you need a frame?
However, for work on paper, it is mandatory to have a protection whether a glass or plexiglass.
2. How do you frame the artwork?
3. How do you place the artwork related to the edge of the frame?
4. How do you place the artwork related to the glass protection?
Is the piece on the back side of the frame or on the front side of the frame, i.e. close to the glass?
A. Back of the frame
