I rarely use any other thread than theirs. Bottom Line is a very thin poly thread. Masterpiece is a 100% cotton.
Bob Purcell has very comprehensive information on threads and needles at the site.

some say if you use polyester thread it will cut through your fabric, eventually. But I feel by the time it does that I'll be long gone and the quilt will probably be in tatters anyway. I too love the thread from Connecting Threads and I also use Star thread.

I like Gutterman 100% cotton - you can buy it at Jo-Anns and use the coupons - in store or on-line. Less linty than Coats and Clark threads

Guttermann is really nice, but way too expensive. I prefer the connecting threads and they have wonderful sales. I have bought several of their sets of colors and always seem to have just the right one to blend. I have also gone to Hancock fabrics and bought the Mary Maxim big spools on sale, they seem to work well too.

I use whatever I have, which is mostly C&C. I would like to buy a set or two of CT thread but not right now. I currently have a larger spool of 100% cotton C&C and my very basic Singer doesn't seem to mind. This thing is a work horse and doesn't seem to mind anything though!

I use Guttermann 100% cotton.

I buy the Coats & Clark machine quilting thread - large spool at JoAnn's when it's 50% off.....which means it costs me only $2.50 a spool.

Hi,

In 1992 I took a quilting class and C & C dual duty (cotton covered poly) was the gold standard for piecing. Coats and Clark hand quilting to quilt the quilt (not sure of the content).

Flash forward to 2008 and now everyone is in the act. I have done a dozen or so since 08, I find the cotton to break easily. I am once again using C & C dual duty, I have used, washed, packed away, used etc the quilt from '92 with no problems at all.

Use what is readily available and cost effective.

I use Coats and Clark all purpose cotton wrapped polyester. Never had a bit of trouble and my sewing machine likes it!

I read in one of the books I have that the reason for using cotton instead of polyester is so that, if there is stress, the thread will break before the fabric will tear. Has anyone heard of Melrose thread?
