I was at a Bernina dealer this afternoon and the new floor models were threaded with Coats and Clark thread. The big 830 had a cone of Signature thread. This dealer sells many different brands of thread but not Coats and Clark. I thought that was odd.

CT thread
 

I use it because I needed different colors for some sewing but I do fine it more linty than other brands. With that said, it makes me clean my machine more often which is a plus.

It's linty but the price really can't be beat and the color selection is great. I've never had trouble with breakage.

I use it mainly for quilting when I want the stitches to show. Also great for doing decorative topstitching, and perfectly good for most piecing work. For really precise piecing or SITD quilting I prefer Aurifil because it's so thin, it can really vanish into the fabric.

I did some price comparisons at my local stores and calculated price per 1,000 yards of thread, just to see:
Aurifil locally goes for $11/spool, @1422 yds/spool that comes out to $7.73 per 1000 yds
Coats & Clarke machine sewing thread locally goes for $2.79/spool, @350 yds/spool that comes out to $7.97 per 1000 yards!

I was shocked that if I buy local, C&C actually costs me more than Aurifil - IMO Aurifil is the Cadillac of cotton thread but it's just a little too expensive for me to try to have a lot of it on hand.

CT thread, on the other hand, goes for $2.49/spool, and @1200 yds/spool that comes out to just $2.08 per 1000 yards of thread - less than 1/3rd the price of Aurifil or C&C. This doesn't include shipping, but who doesn't spend the $50 minimum for free shipping? LOL

CT cones, by the way, come out to $2.00 per 1000 yards, which also surprised me because isn't that much of a savings and they don't seem to come in that many colors. I love how inexpensive the smaller CT spools are - I can afford to have a literal rainbow of thread on hand at all times. :)

Many people do well with Connecting Threads thread, and it's a good buy. I used it when I had my Brother sewing machine, and had no problems. Then that died, and I bought a Janome. I love my Janome MC9700! But it does seem to be fussy about threads, and the Connecting Threads thread made my bobbin so linty that I had to clean it every time I changed the bobbin. I switched to Masterpiece (for piecing) and King Tut (for FMQ). That solved my "linty" problem, and I love the thread! It is pricey. On the other hand, I bought a BIG cone of pale grey over a year ago, and have been using it to piece almost everything. There is still lots of thread on the cone as well, so I know I'll get a lot more piecing out of it. Bought that way, it's really rather economical. I buy the small spools of King Tut for FMQ, as I never know when I'll need that color again. All Superior threads are awesome, IMHO. If I'm just practicing, I have some Coats & Clark I use, leftovers from earlier projects. So it depends: if I'm working on a project, I'll use the Superior threads. If it's just some small thing, I use the cheaper stuff.

When using CT thread I have to use a larger needle. So far I have liked their thread.

I purchased one spool..what did I have to lose? Well I am glad I only got one. It a lot thicker than the Aurifil that I use. Went back to Aurifil only. I am sure it has a lot to do with the machine. Both of mine are Janomes and they do not like it at all. At least mine didn't. So buy one and try , the price is right for sure!

Hello! I use CT 50wt on my quilt machine and it works just fine. Maybe a little linty but I think most threads are. I also use Aurifil when I can find it on sale as it is a little pricey. Any thread left on the bobbins from both threads I use for piecing so none is wasted. Right now I'm going thru a bunch of my regular threads as well as the threads that came with my quilt machine for piecing as I didn't care for how they worked on the quilt machine. Its supposed to take any thread but if I have to fiddle too much to get the tension correct, I go back to my old tried and true threads which is either CT or Aurifil. I did pick up some of CT polyester threads in the large spool but have yet to try it out. If my machine doesn't like it either, then it will be used to piece with. Our hobby, in my opinion, is too expensive to waste any of the stuff we use for it such as fabrics, threads, stabilizers, etc.

I have used auafil and gutterman before I discovered connecting threads. I find connecting threads the best. I do not find it too linty and it is strong. None of my seams have opened up because of the thread breaking

I have a janome machine and I use mostly ct thread

I too use CT 50 wt cotton for piecing. It is consistent and my Ellisimo likes it. I bought a few cones of the new poly for FMQ and my Tiara loves it. Emily, FL
