The difference between Aurifil and King Tut is that Aurifil is a long staple cotton and King Tut is extra-long staple cotton. The difference is huge and I have found that Aurifil is not a good choice for LA quilting - it breaks all the time because it's not strong enough. I save the Aurifil for piecing and use King Tut for quilting. Love the variegated colors offered by King Tut!!!

Great idea! I never thought of that. I'm going to give it a try on the next quilt!

Love Sew Fine for ALL of my quilting needs- It's polyester that feels like cotton, but very thin and strong. I use it in top and bobbin for machine quilting on my Gammill as well as for all my piecing. I like a thread that sinks into the fabric - flatter seams, more precision on points, beautiful piecing.
