I had no idea how much I needed this!  How incredibly handy to have several threaded needles on the ready for binding quilts or hand piecing (or, I'm sure, a multitude of other reasons I've yet to use it for).  Instructions are a little skimpy, but for the most part it is fairly self-explanatory.  I have been using it with John James needles size 9 with no problems at all.  I am pleased with this item.
