Coats is pretty cheap thread but my machine does fine with it. I use it for piecing and higher quality for machine quilting.

I have not had any problems with it.

I've always used CC threads. The only trouble I've ever had was when I tried the machine quilting thread; it kept breaking. I switched back to the dual duty for machine quilting and had no problem. Holds up just fine. My grandkids' quilts have been washed dozens of times and they're still holding up.

I use there thread for quilting and there embroidery thread for machine embrodery. Sometime you can get it at JoAnn's for 50% off

I use it all the time and don't have any problems with it!

C & C just makes too much lint for my machine.

Used to be alright for a lower-end product. Now they have changed how they make the stuff and it's awful--thick and wirey---I wont use it.

I've never had any issues with it at all. I also use Connecting Thread's thread.

I had a friend who worked at Hancocks and she said they had many complaints about Coats and Clarks thread after it's place of manufacture was changed (Was it to Mexico? hmm, can't temember). I have never had any problems with it myself.
Contrary to popular belief, it does not hurt your quilt to use cotton wrapped poly thread. Some quilters will tell you that poly cuts your cotton fabric. it does not. The fabric may wear out before the thread is all.

I machine quilt with the Pfaff Grand Quilter - tried all sorts of threads - they all seemed to break when I have half way through a row of quilting - someone told me to try Coates and now its the only thread I buy for quilting - the cotton thread - no breaks, no lint, lovely stitches. I use it in the bobbin as well....
