Thanks for the information on the Teflon material from Bed, Bath, & Beyond. I live quite some distance from the nearest quilt or fabric shop so I am always looking for good ideas. I read an article on Superior Threads which addressed tension issues lately. One piece of good information mentioned thread breakage which was one of the hair tugging problems with my machine when I was first "Free Motion Quilting". It said to take notice of how the thread is feeding from the spool. Often, it just needs to be turned around so that the thread feeds from the opposite direction. Also some thread will feed better if the spool comes from the back on a free standing holder. Look at how the thread is wound on the spool. I use a top stitch or stretch needle as the eye is larger and slanted differently which works well with faster speeds. JC
