I have no problems--lucky, I guess, but this is how I do it. I use a 14 top stitch needle, I have mineral oil in a nasal spray bottle and run the tip down the side of the spool about 3 times (being frugal--just lightly spreading), then I put my thread on a stand away from the machine , giving the thread enough length to unwind the coils out. I've not had any breakage in quite a long time--since using the mineral oil. It may be basically what "sewer's aid" is composed of--I don't know...I have both, but prefer the above. If anyone can tell me this is bad for my machines, I will toss it immediately and look for another solution!
