Seraflex Stretch Thread - royal blue

(1 review) Write a Review


Mettler Seraflex stretch thread - 130m 

A new sewing thread suitable for Sportswear, Underwear and jersey garments.

Made from 100% PTT (renewable raw material), Seraflex allows elongation of approx. 65% making all seams highly elastic. 

Works best using a straight stitch and 70-80 size machine needles.

Use for both main thread and bobbin, loosen thread tension for best results.
