The custom drawings are on standard acid-free drawing paper. If you would like to have your drawing mounted to a mat board (this is super thick, specialized poster board designed specifically for framing* artwork) I can do that for you. Since the mat board prevents the drawing from being able to be rolled in a parchment tube, this increases the cost of packaging and shipping as well, which is included in the cost of the mat board. If you have a color preference please tell me, otherwise I will generally use black or grey to bring out the details of pencil drawings, for oil pastels I may choose a different color that accents the artwork.
*Note: I do not offer framing services at this time, only mat board.
