Guess I am odd man out. Tried a cone and didn't like. Used it up and was quite happy when it was all gone. It did run fine, I just didn't like the looks of it in the quilting. I am a Glide girl, love that stuff and pretty much use it exclusively as well as the magnaglide bobbins. I do use some specialty threads like Invisifil, Monofiliment (either Superior Monopoly or Filtec Essence) and I do have several cones of King Tut but not a big fan of quilting with any cotton thread due to lint. I also have a few cones of bottom line and so fine but my thread of choice is almost always Glide.
