INSTRUCTIONS FOR MAKING UP THE FABRICS AFTER THEY 

 ARE VULCANIZED. 



If any elastic cement could be found that would unite 

 these fabrics firmly, so that they could be made up as expe- 

 ditiously as they are made at the factories before thev are 

 vulcanized, and also equally impervious to air or water, it would 

 be an invaluable acquisition. This can with no more reason 

 be expected, than that a thing can be adhesive and inadhesive 

 at the same time. 



The great object so long sought after, that of divesting gum- 

 elastic of its adhesive quality, has been so completely effected 

 in these fabrics that they cannot be made again adhesive even 

 when it is desired. 



The following directions in relation to making up various 

 articles described in this work, from the different fabrics which 

 are to be found in the market, may be found useful. 



When a button-hole is cut, either in the drapery or metallic 

 compound, care should be taken to cut it at the lower end, with 

 a round punch, to correspond with the size of the shank of the 

 button or knob with which it is to be used. A simple, straight- 

 cut button-hole will tear out more easily. 



Whenever the fabrics called elastic compound, or drapery, 

 are stitched to other fabrics, a stay of leather, vellum, or some 

 other firm goods must first be cemented to it, or the stitch will 

 not hold. 



Fish or other glue, is the strongest cement that can be 

 used for these goods, when they are not to be exposed to much 

 wet. Dry heat will not injure this cement. Any of the coated 

 cloths, and also all the laminated fabrics, may be stitched with
