4. That black background was a bit of a problem, I needed to remove any excess pastel so that there were no issues with pastel movement during framing. My extremely talented framer achieved this without problem, placing a slip between the frame and the glass so the two do not come in contact (this is done for any of my pastel paintings that do not have a mount). I do not spray my paintings with fixative as it can cause colours to change over time, so I need to know that the pastel is being held fast by the toothed paper.
