I only read about a dozen posts, seems there are a certain number of people always post the same thing about the high end threads. I wouldn't know them if they came up and introduced themselves. About all of my threads are Coats and Clark ot essentials from Connecting Threads. I have many,many spools of it and I use it all the time, I do quilt lots with a machine quilting thread. If I get lint of the thread I just clean it out. I brush out bobbin area with every bobbin change. Only takes a few seconds.
