Now let's look at the flip side. Glass may be easier to clean, but sprayed boards are pretty resilient. They are essentially waterproof, so all that is needed is a lightly damp cloth (not paper towel, because that will leave paper towel dust all over it). But perhaps the best reason that I prefer no glass is, quite simply, you can see the drawing better! I float my boards in the center of an off-white mat (if it is a color piece I might choose a different mat) with a simple black wood moulding. This way, you can see the whole board, sides and all, which makes it more like a painting on canvas than a drawing. It stands out, and makes you want to touch it. In fact, last fall I participated in the local studio tour, many of my visitors made that very comment.
Below are two photographs of my framed work. The first is behind glass, the second is not. For best comparison, both pieces are the same size, photographed on the same wall in the same light conditions. Ultimately, the choice is yours.
