Our threads are made of high quality viscose rayon - a cellulose based product. 
Viscose rayon is a most flexible embroidery thread which can be laid in every embroidery direction and prevents thread looping. 
These 40wt threads come in rich brilliant colours, have a soft feel, high tensile strength, uniform twist and an excellent sewing performance 
Some Hints
    |  | Embroidered garments should be washed in mild detergent. | 
    |  | Do not use bleach or stain removers. Do not dry clean. | 
    |  | Never leave damp embroidered items folded or pressed together as thread colours may bleed. | 
    |  | When ironing, use a cool or medium setting. | 
    |  | Store your threads in a dry ventilated place in boxes to protect from dust and moisture. | 
    |  | Our rayon threads are on a spool. Unwrap the cover carefully as the thread is high sheen and slippery. | 
    |  | Keep the cover and the label for reordering. | 
    |  | Use on a horizontal or vertical spool holder, taking care that the thread flows smoothly. | 
    |  | Loosen your top tension and for best results, we recommend topstitch needles size 90 or 100. |
