Loved reading all the good reviews. I use the Essential Pro, which is the poly longarm thread, all the time as don't like the lint of cotton. It makes a great piecing thread, I keep lots of bobbins filled with silver, neutral or dark gray to do all my piecing, it is thin and strong. Since so many of you like the cotton cones, I will be trying those. My Innova will adapt to most threads. CT gives very good service in my experience.
