The cotton from Connecting Threads is linty, so if you used that you would have to adjust the tension and make sure your needle is suitable. There is a huge difference in threads. Many different threads and posts on here addressing this. This is me, as everyone has differences and favorites, but I prefer polyester thread over cotton for my piecing. It is stronger.Simply google Superior threads, Isacord, Sulky, Aurifil, and evenn Connecting Threads Polyester and also ThreadArt/polyester thread. You will see differences in price, but they are all very good quality for quilting, embroidery, and even everyday sewing. My projects have been proving it for many, many years of sewing. Also, in my honest opinion, I will never ever use C&C thread again. Ever. Not worth the cheap price. I have Brother machines, Babylocks, and have sewn on Kenmore and Singers. Good needles and the good threads are always a given.
