I use Coats & Clark for most all my sewing. The only problem I have is sometimes when I'm hand sewing it will get weak at the needle. I have to remember to move it every so often so it moves down the thread. I know one prize winning quilter who uses C & C exclusively because of the little wisps on the thread. It makes the quilting look better for her. I've taken a class from her and she says it is the best thread for her to use.
