406 COPYING DRAWINGS. 



Stenciling. 



Lay the print or drawing you wish to have 

 copied, over a sheet of paper, and with a pin or 

 needle prick all the outline over with holes, through 

 both the papers. Then take the clean paper with 

 the holes made in it, and lay it upon the paper you 

 wish to have the design transferred to, and dust it

 bag; the dust will penetrate through the holes, 

 and leave a correct copy of the original upon the 

 paper. 



This pricked paper will do again for any number 

 of copies. This is very useful for ladies who work 

 flowers upon muslin.

 lines across with a black-lead pencil from side to 

 side, and from top to bottom. Then having your 

 paper of the size you intend, divide it into the same 

 number of squares, either larger or less, as you 

 would enlarge or contract it. Then placing your 

 original before you, draw, square by square, the 

 several parts, observing to make the part of the 

 figure you are drawing fall in the same part of the 

 squares in the copy, as it does in your original. 

 To prevent mistakes, number the squares both of 

 the original and copy. This method is much used 

 by engravers. 



To prevent the necessity of ruling across the 

 original, which in some cases may injure it, take a 

 square pane of crown glass, and divide its sides, and
