I have most all their colors in both cotton and polyester. Use it exclusively for quilting. True the cotton is very linty but I feel most all threads have some lint. I just have to remember to clean out the bobbin area and around the needle area at every bobbin change. I usually keep at least 3 spools of every color so I have one for the bobbin winder and 1 on the machine. If its a color I use alot I'll keep up to 10 spools as you never know when they'll stop selling that particular color. I also have Aurifil too and have used that for both piecing and quilting.
And yes, I love the price of CT's threads.
