Aurifil is my thread of choice but I have some King Tut thread left that I still use for quilting. It is a good color for what I need, working with Christmas fabrics currently, and I like it as does Sarah. She is my Singer 15-91 that I'm currently quilting with because she's in a cabinet. I have used Presencia a bit. It is a polyester thread that isn't linty and slides smoothly through my machine plus it's very fine so the bobbins hold a lot of thread. I just prefer cotton over polyester so no longer use it but will recommend it to others.
