That was the first thing I suggested. Use your metallic thread spool holder or if you have another spool holder, use the invisible thread on it. I have nad no problem since doing that. I also prefer the Polyester over the nylon, it is softer & the cut ends don't 'pick'! I use Sulky polyester & the only trouble I have is being able to see it!!! :oops: Itherwise, it's great!
