TO PAPER ON A BOARD PARTITION.
When paper is pasted on boards, it must crack, when the lumber shrinks. If you paste cloth over the cracks, it must crack, if the cracks open further than the cloth will stretch. When you tack cloth on a partition and size it, if the size goes through the cloth and sticks it fast to the boards, it will be likely to crack when the lumber shrinks. For a good job I would advise that you first cover the partition with paper tacked on, then when you size the cloth, it will stick to the paper, and not to the boards. I have met with uniform success in this way; because the boards are left free to shrink and swell without breaking the cloth or paper. I like to sew the cloth together with a running seam in pieces large enough to cover all broad spaces, turn the smooth side out, stretch well, and fasten the edges only; drive the tacks an inch from the edges of the cloth, so that you can fasten them down smoothly with paste. When a man has been unwise enough to put a board partition across one end of an otherwise fine room, and is willing to pay for his folly: first, take measurements of the blank spaces, and sew together some fairly strong unbleached muslin, stretch on frames, and give it a coat of glue and alum size, and whiting; when dry, carefully fit each piece in its place and tack it an inch from the edges and fasten the edges down smooth with strong flour paste. Tack only at the edges, and if you are careful to butt edge the different pieces over the doors, etc., you can make a nice smooth job in this way. By using this method the paste will not stick the cloth to the wall. Use tinned tacks to prevent rust.
