I quit C & C quite a long time ago after all the fuzz and slubs/flaws in the thread itself--got tired of re-threading the machines!
Right now I am using up about 20 HUGE cones of unlabeled cotton thread from a sewing shop that quit....wish I knew who made it--it is GREAT thread.....they must be 15,000 yard cones, and most are at least half full--got them on eBay five years ago and they cost $2 cone.
