I use 505 or Dritz. The Dritz is available at Joann's and is "couponable" (my word).
The Sullivans - well, I could feel that killing my brain cells as I sprayed it. :shock: That was years ago, so maybe they've changed their formula.
But the Dritz has been working very well. And I've never had gum-up on my needle from using a spray.
