I don't like it for anything but serging because it just isn't as uniform as other threads. Take a look at it under a bright light and compare it to "regular" good quality thread - it just isn't the same. It works great for serging because you use 3-4 threads together, but in piecing or quilting you are using only 2 threads (top and bobbin). It certainly isn't the worst stuff in the world, but there are more uniform options. BTW, uniformity matters in things like setting tension and thread breaks.
