Give the framework, screening, shelves, and top and bottom 

 pans two coats of flat white paint. Give plenty of time for drying 

 between coats. When the flat paint is thoroughly dry, apply two 

 coats of white enamel. Remember that the success of enameling 



a surface depends largely on allow- 

 ing sufficient time for drying 

 between coats. 



Before applying the second coat 

 of enamel, be sure that the first 

 coat has lost all trace of stickiness. 

 The amount of time necessary 

 between coats depends on the con- 

 dition of the atmosphere. It may 

 be several days before you can 

 apply the last coat. Remember 

 that you want a hard enamel sur- 

 face, and the only way to produce 

 it is to exercise enough patience 

 to allow thorough drying between 

 coats of paint and enamel, and a 

 final "thorough drying before the 

 cloth cover is attached to the 

 frame. 



A covering of canton flannel, 



Courtesy of U.S. Department of Agriculture, burlap, Or duck should be CUt and 



hemmed to fit the case, as in Fig- 

 ure 14. If canton flannel is used, 

 have the smooth side out . About three yards of material are needed . 

 This covering should extend down to the very bottom of the case. 

 Button the cover around the top and bottom of the frame with 

 buggy hooks and eyes. Another way to button the cloth to the 

 frame is to sew large buttons firmly to heavy strips of cloth at 

 desired intervals, and then tack these strips to the edges where the 

 cover is to be buttoned. On the edges of the covering provide 

 buttonholes at intervals corresponding to intervals between buttons 

 on the strips.
