I found the thread that came with my Innova, my machine didn't like so I use it for piecing on my regular machine. Hate to waste it. Which tension system do you have on your machine? I ordered the upgraded tension assembly as I wanted the least problems with tension. So far so good. I do from time to time my thread has jumped behind the thread guide just after the tension disk causing it to get trapped and then break. It also kept jumping out of this thread guide as well as the next one in line so have altered those guides so the thread can't jump out. Saves a lot of frustration on my part. As mentioned by others, find a thread your machine likes and stick with it. My metallic embroidery thread is loved by my Innova but not by my embroidery machine...GO FIGURE!!!! Its just a trial and error for us.
