I've found that C&C just isn't the quality that I was used to. I've picked up a couple of spools recently and they had slubs along with thin spots in the thread. I broke a needle when it got to one of the slubs(thick spots). I threw the rest of the thread in the trash.
My favorite cotton thread is Aurifil and polyester is Metrosene. I'm fed up with wasting money on poor quality thread. I've been sewing since 1966, quilting since 1988. It's sad that brands that were wonderful have become junk.
