C&C is very expensive for the not so great quality. I don't use it. Connecting Threads cotton is a thick 3 ply thread. I prefer Connecting Threads poly on the cone. The best cotton thread is Long Staple Egyptian Cotton. I use Aurifil and Superior the most. If you have access to microscope (the kid's toy one will work) look at the different threads. You will be amazed at how some look like barb wire. You don't want that going through your machine.
