I tried it and thought it was ok. Then I noticed that I kept having thread breakage and an awful lot of lint in the bobbin case. I must have 30+ spools of this stuff now. One day I needed white thread and the only one I had for quilting was a spool of the Mettler silk finish cotton. No thread breakage--not much lint. Now I want to go back to Mettler. It is much more expensive but I don't have the grief with it. I change needles 2-3 times while quilting and oil my machine at least once before and during a quilting project. I have tried Aurifil and my machine does not like it. Now I find out that
the connecting threads is not to my liking.
I am now on the search for a good price on Mettler silk finish cotton 500 yard spools in 50 wt. I guess I will try to sell
a bunch of these threads from connecting threads.
My advice is if you are going to place an order with connecting threads, try one or two but don't do what I did and buy a bunch of them until you try it. Everyone is different and every sewing machine is different.
