and window of average size. Make no allowance for small 

 openings. This will give a fairly approximate estimate 

 of the number of single rolls of common wall paper required. 

 This makes allowance for trimming and matching. 



For example, suppose it is desired to find the 

 number of single rolls of paper needed for a room 12 feet 

 .vide, 15 feet long, with wall 10 feet high; also the number 

 of rolls of border required. The distance around the room 

 is 54 feet. 



10 x 54 = 540 Sq.ft. wall surface 

 15 x 12 180 " " ceiling surface 

 540 +180 = 720 " " total 



Suppose there ere two doors and three windows of 

 ordinary size in the room. 



20 x 5 100 Sq. ft. of opening surface 



to deduct 



720 T 100= 620 " " to paper 

 620 7 30= 20-2/3 rolls or 21 rolls of paper 



QUANTITY 0? BORDi-SR N3EDED. 



Since the distance around the room is 54 feet or 

 18 yards and a two strip roll of border contains 16 yards, 

 1-1/8 rolls of border will be required. 



.THINS. 



Use ordinary unbleached muslin of medium weight 

 1 yard wide. There will be needed as many running yards a. 

 there are square yards of surface to be papered. 



TACK3. 



Order 4 oz. cut tacks. One pound of tacks will 

 tack about 6 square yards of lining. Tack lining at 1 inch 

 intervals along edge and scatter tack it throughout.
