I've been using their threads about 7 yrs, have many of the sets and love the thread. Lots of color choices, and you can't beat the price. The company is wonderful to work with. They are always eager to help with any questions or concerns, great customer service.
Mostly I use it for piecing, on my fabric postcards that I make. I do have other brands
Altho I do only use Superiors Bottom Line thread in my bobbins, while using Essential as a top thread.
