As a crucial part of the sewing craft, thread often deserves more attention that it gets. Just like everything else, there are high and low quality threads.
When higher quality threads are made, they produce scraps. Lower quality thread is often made out of those scrap fibers, to reduce waste. The unfortunate side effect is that using these scraps produces a rough, weak thread that is prone to producing lint inside your machine. That lint can cause inconsistent tension and stitching. Due to being made of scraps, the thread will deteriorate quicker and break more often in the middle of a project.
