The following method will be found useful, especially if you want to exhibit a crayon without the expense of framing it. Lay on the mounting board a piece of heavy manilla paper somewhat larger than the picture, then put the crayon on this face up, next the passepartout, and last the clean glass. Mark the size of this on the paper, and then, having removed the glass, crayon and passepartout, cut the paper enough larger than the marks to allow it to come up one inch all around over the edges of the glass; next dampen the paper, and apply the starch paste to its edges about six inches all around, then lay the crayon, passepartout and glass back where they were on the paper, and bring the latter up, lapping it over the face of the glass; cut the corners out so as to bring them over properly; rub the edges down thoroughly on the glass, and with a ruler and knife trim off the paper, allowing one-quarter of an inch margin; then set away to dry. This will put the crayon in good condition to be exhibited, and will thoroughly protect it.
