Some of my vintage machines only like Coats and Clarks, but the Janome likes the Gutterman. For me, it comes down to what works well with the machines.

I use thread from Connecting Threads and love it. My Juki works well with it.

I don't spend much time worrying about brands of thread. If it is strong, (pull it to see if it will break easily, if so pitch it.)and the color I want and a weight that is suitable and my machine doesn't act up, I will use it and be happy!

i tend to use C&C - just habit. I can get away w/ just a natural, black, and tan color to take care of most things. Natural is what i use the most.

I use what I have on hand and have had good luck. But I do have a tendency to go to the Connecting Threads thread I have bought and love it!

I use Gutterman and Mettler. I dont have a problem with my Janome. My friend is pickier and will only use Aurifil. Whatever....I think I am buying that 200 spool deal.

I have used most all brands of thread. The best thread ever is silk but it's not practical money wise for general sewing. I like Connecting Threads and have a lot of it. I like Coats and Clark metallic, it never breaks or frays. Superior Sew Fine and Bottom Line is great for bobbins. Glide by Fil Tec is excellent for machine quilting. I have discovered InvisFil threads and it is almost like sewing with silk. I watch all the thread sites and when a great clearance price is on a set I buy it. I got four sets of 8 mini king cone spools of Aurifil thread for $16 each and can only say it's good thread but not worth me paying the full price

I just used the vacuum cleaner attachment to suck out the "felt" under my needle plate. I'd been using C&C thread lately. I couldn't believe how much lint was crammed in there.
I'll be using something else from now on.

I don't care for Coats & Clark or Gutterman. Both are too linty, and my machines don't like them. Mettler works great, and Aurifil is fabulous!!

That's funny that the lady from Joannes said C&C was "nice" thread. LOL. It's reputation is the bottom of the barrel.
