100% Cotton Thread, 35 Weight (Heavier) for Quilting and Sewing

Due to customer demand, Marathon Threads Canada now stocks 100% 35 weight cotton thread. This long staple cotton thread is great for handwork or machines. This strong 3-ply thread can also be used for long-arm quilting and industrial machines as well. The mercerizing process used in making these 3-ply thread leaves less fluff and lint in your machines enabling them to run cleaner. Ideal weight for decorative stitching projects, embroidery or quilting! This new product is carried in 1,000 mtr. (1,100 yd.) cones. Please see the chart below for available 35 weight colours.

100% Cotton Thread, Lighter Weight for Quilting and Sewing

Marathon Threads Canada now also stocks 100% lighter weight long staple cotton thread for general sewing, embroidery, quilting, or serging. Great for quilt piecing. Perfect to add a special touch to all your decorative stitching projects, too! Since it is mercerized, a smoother, high quality thread is manufactured causing less wear and tear on the machine. This beautiful thread is available in both 1,500 mtr. (1,650 yd.) and 3,000 mtr. (3,300 yd.) cones. Please see chart below for available lighter weight colours. Please note that the following colours are only available in 40 weight.
