For two years I had problems with my Bernina until I bought a cone of Gutermann thread. Then, all my problems vanished. It was the thread all along. And I think my machine likes cones, also. So, I have tons of varigated thread (which my machine hates) and all other expensive thread that I can't use, but it's fine by me as long as my sewing machine is running smoothly finely.

I have a Janome 6600 which despises my Gutermann thread. It will clog up and make huge birds nests over and over again. I took it into the shop about 2 dozen times when I first bought it. We finally just decided nothing was wrong with the machine, it's just very picky about thread. I've had to change to Aurifil. I have so many spools of Gutermann, so I just use those on my Featherweights.

My Janome doesn't like Janome thread. That's strange because it's a Janome machine. Oh well! At least it likes C&C for embroidering.

My Viking Husqvarna doesn't like C&C so I use G too! Gave away all of my C&C years ago and then I got a couple of vintage machines - they like C&C just fine so I'm back to using it in them. Still have to buy G for the picky Viking but I only buy it when it's half off at JoAnn's! But then, I only buy the C&C when it's half off too...... :-)

Lately i've been using C&C poly on poly thread in my bobbin. I must use it up and so far its' working well.

Golly - I have two quilts that are 20 years old that are our couch quilts - translation - used a lot - sewn on a Pfaff 1471 - using C&C cotton covered Dual Duty thread - there are NO popped seams, NO cut threads/frayed areas on the seam lines caused by the thread - I don't recall any major linting from the THREAD - some fabrics I've used shed a lot of lint.

I have no experience with any machines newer than my Pfaff 1471 - so don't know how picky they are.

So - if any one wants to give away their cotton covered C&C dual duty thread - I would be delighted to pay the postage to get it here!

I use C&C 100 % egyptian cotton thread in all my machines which include the Diamond, SE, Sapphire, Pfaff 4.0 and all my Singers and never had a problem...I know Viking and Pfaff recommend "G" for their machines..I happen not to like "G" thread. The "G" thread makes a fat thread stitch on my machines... Funny, My embroidery machines don't like Sulky embroidery thread.

My babylock hates coates and clark threads. Luckily I have other machines that do fine with it so I didn't have to toss it. Weird how different the machines can be.

My old machine is a Pfaff and it flat refused to sew using anything except Gutterman thread! I just bought a Janome MC6600p and it seems to do just fine with almost anything I'm giving it! YAY!

When I took a beginning sewing class I learned about thread and "slubs". Some thread is very "slubby", if you hold it up to the light you will see a lot of nubs along the length of it. This is what shreds and gums up the works. I went home and looked it up on the internet and found a site that had different threads under a magnifying glass and C&C was one of the worst offenders. Gutterman and Mettler were the best.

Since then I have heard Coats and Clark have improved, and I bought some 100% cotton for my last two projects. The thread broke more often and the machine had a lot of lint to clean out, but it did work.
