First, I don't quilt with 100% cotton thread. It breaks too easily for me. I had problems with some stronger polyester thread when quilting with my older Nolting (no computer, all manual, must oil every time you use it). The thread wouldn't feed easily. I happened to meet Sharon Schamber at one of the Houston Quilt Festival and to my surprise, she had a spool of thread soaking in some oil. I asked her about it and she said she did it all the time. I couldn't believe that there wouldn't be an oil residual but she said that running the thread though the tensioners would squeeze out any excess oil. I tried it and loved the ease of the thread going the machine. I would get my spool out of the oil and let it rest and drain overnight before using it. I used machine oil, the same as I was oiling my machine with. I was happy with the results.
