After reading the comments, I decided to post a short addendum. Yes, the Aurifil I use is 28 wt. I had previously thought all were 40 wt. I checked the Coats & Clark website and found that their hand quilting thread is a 20 wt, which may be the real reason I don't like it...too thick. I was surprised at the Aurifil because it is very similar in feel to the King Tut, which is a 40 wt. It all comes down to personal choice about the feel and ease of use. Although I need to be thrifty when selecting quilty notions, I would still choose the Aurifil....after I use up what I have of course. Why? because I quilt for the pure enjoyment and the Aurifil meets that criteria.
