I am neither for or against using serger thread. Might try it since many WHO have tried had no problems. I believe that personal testimony is of greater value than reading an article written by a company which is in the business of selling thread to quilters. Whose bottom line are corporations and businesses selling products looking out for? Of course a three ply thread is going to be stronger it also has more materials i.e. more money. But really does it cost THAT much more for one strand of thread? I wonder how much of this debate is really just hype?
