This Gütermann MaraFlex 120 Tex 38, 1,640 yds Stretch Thread is a continuous filament thread that offers maxium seam elasticiy for woven stretch applications. Used in chainstitch or lockstitch machines. Suitable for stretch woven fabrics used in garments that fit close to the body and demand motion or stretch. Ideal for visible elastic decorative seams, and highly-elastic woven and knitted textiles.
Love this thread for top stitching knits with a straight stitch instead of having to use a zigzag. It doesn't seem that stretchy but it has just enough give to make a difference. I have tried Coats and Maxilock stretch thread but they seem to jam in my machine so I plan to buy this in more colors.
