I've been using C&C Dual Duty Plus threads, and have a lot of problems with lint buildup in my Brother CS6000i. Will use them up, and slowly try other brands. I wonder how much of the linting problems may be due to chafing in the needle eye?

It is good quality. Your quilts will hold together for years. I wouldn't hesitate to use it. The only problem with C&C is that it tends to shed more lint than other threads when you are machine sewing with it. Part of this is caused by the machine - I have MUCH more lint from my Bernina than from my Brother using the same thread. For this reason, I am using up my C&C threads (I have hundreds of dollars worth) and will replace it with either Aurofil or other brand which result in lower lint. Much more expensive though.

As much as I love my Bernina, I was not expecting to be forced to spend a lot more on thread.

My Baby Lock is not persnickety when it comes to thread, but I was using up some regular C&C and she threw a fit. Now I like to use the Star variegated thread which is made by C&C and no problem with it whatsoever.
