Same here, I've use Coats & Clarks 100% cotton thread and find it very satisfactory. I've use Gutermann and others and don't seem to get the same satisfaction as the C & C. at least for quilting. For embroidery I use the 100% rayon thread by Iris...don't even know if its made any longer but have a well preserved stock of it for the amount of machine embroidery I do. I've been told that you need to keep your thread in the refrigerator if you are not going to use it for long period of times which I have done with my embroidery thread. I use my 100% cotton thread too much to keep a stock of it.
