Making Artistic Decorative Butterflies 

 in Sheet- Copper 



TO produce artistic effects representing 

 butterflies in copper requires a little 

 skill, a sheet of copper — about 20-gage — 

 a jeweler's saw-frame and blades, artist's 

 oil colors ground in light Japan, two camel's- 

 hair brushes — one wide and the other 

 pointed — and a fine drawing- 

 pen known as No. 390 

 The colors of paints 

 and inks used de- 

 pends upon the de- 

 s i g n to be 

 executed. 



Select the 

 butterfly, or a 

 colored drawing 

 of one, to be re- 

 produced in metal 

 and very carefully 

 trace or draw the out- 

 line on a piece of the 

 copper. Saw it out, follow- 

 ing the outline closely. Hold the 

 copper in a bench-vise, or by means of 

 a bench-angle, such as used by jewel- 

 ers, or like that shown in the illustra- 

 tion. If the saw tends to bind or 

 chatter rub a bit of beeswax or com- 

 mon washing-soap along the teeth. 

 Smooth the edges of the copper 

 pattern with a fine flat file and go 

 over the surface with very fine- 

 grained emery paper. 



The coloring is next in order. Suppose, 

 for example, the butterfly to be reproduced 

 is yellow with black-lined wings and body. 

 Squeeze a little of the yellow oil-color on a 

 piece of glass and mix it to a fairly thin con- 

 sistency with the Japan drier. Dip up a 

 good brush full and flow it e\-enly over the 

 entire surface of each side with the widest 

 brush, allowing one side to thoroughly dry 

 before touching the other. Choose the 

 smoothest side and with a well-pointed 

 pencil trace very lightly the general mark- 



ings on the wings and body; then with a 

 pen and ink, copy the markings of the 

 original as closely as possible. This ink 

 will dr>' almost instantly and leave a dull 

 surface. If a glossy surface is desired give 

 it a coat of very thin white shellac. Spots 

 of contrasting colors can be touched in with 

 the smaller brushes. 



An assortment of these varicolored flies 

 will make attractive pieces which can be 

 utilized for many purposes, such as 

 bookmarks, pendants, etc. By solder- 

 ing a buckle-strap to one side before 

 painting, an attractive and original 

 belt-buckle can be made. Solder a 

 sharp nail to the under side and 

 drive in one end 

 of a stick stained 

 green and use for 

 a plant stick. 

 Several of these 

 plant sticks sup- 

 porting an 

 assorted lot of 

 brilliantly colored 

 moths and butter- 

 flies, placed 

 among the leaves 

 of potted plants 

 furnish a beauti- 

 ful and realistic

Repairing Automobile Tires to 

 Prevent Bulky Places 



LKY-LOOKING repairs are often 

 caused by the overlapping of the new 

 plies of fabric on the old. When a piece 

 of fabric is inserted it should lap just 

 ^s in. all around. During vulcanization 

 the air pressure and the expansion of the 

 tire will draw the fabric down so that it 

 will join the old fabric exactly without 

 overlapping or any clumsy eflfect.
