Robison-Anton's Rayon is a 40 weight twisted thread that comes in over 370 brilliant colors. 
It is ideal for embroidery applications that call for high luster and silky, smooth feel (or hand). 
It is processed from top-quality, high tenacity (strength) rayon filament. 
This results in a superior sewing, fewer thread breaks, and excellent stitch appearance.
