So Fine #40 is variegated polyester thread with precision-dyed 1-inch color change intervals. More importantly, it is a wonderful thread to use for topstitching. The fiber is an innovative polyester that grasps onto fabric well and when sewn or quilted with proper tension, makes wonderful stitches. The nature of So Fine thread is different from any other polyester thread. The smooth, lint-free processing it goes through is a patented and protected process. This makes So Fine #40 thread the only thread like it in the world. The weight of thread being a #40 is ideal for topstitching when you want to see the design of the thread. With 35 colors and growing, you will find the top trending color variations within this line.
So Fine #40 is the most recent addition to our family of So Fine #30 & #50 threads.
