Thought I should share how I am presenting the cat portrait. I added a 3/4" mat and lifted the pastel from behind the mat so that any accumulating dust falls behind the mat. This is usually standard practice when framing pastels. I'd also like to mention that I did not use a spray fixative on this particular pastel. I do, however, like to give a light spraying of fixative when I ship unframed pastel work.
