Most of the machine quilting thread used by professionals are poly or silk. The better poly thread made now is no longer considered bad for cotton fabrics. It's a matter of preference but don't dismiss poly because of what was thought about it years ago.

I hate polyester. I don't buy clothes or anything made with it. I wouldn't want it in my quilts either. Personal preference.

I don't wear polyester clothing either, it makes me hot and
sweaty. Cotton or linen is much cooler for clothing.

I remember the 70's polyknits. It was and still is plain awful!

It was geared toward long arm quilting, but I see no reason it could not be used in a domestic machine. King Tut is geared toward long arm machines, but a lot of people use it in their domestic machines.

Essential is made of 100% European Cotton. Essential Pro is polyester covered. If they made Essential Pro in cotton they would be selling two thread each with a different name.

I might try this. I'm having trouble with my Janome that was just serviced, call my LQS for help and she asked what kind of thread I used. I told her Connecting Threads product and she said "that's not good thread and might be the problem". I've used their thread for years and never had this problem before. I might give their new line a try, thanks.

Connecting Threads also offers Essential thread for regular machines.
They also offer great deals on fabrics with batiks at $6/yd, and a line
called quilter's candies of marbled colors that have been a great boon to
my quilting. They have excellent video tutorials if you click on
Karen's page.I highly recommend them. - Judy

I looked at CT cotton threads under a microscope and believe me you can see every flaw. The highest price cotton thread I have (Aurifil) looks the same as CT thread. I was amazed at how many slubs there were in every brand of cotton thread I have. You can see exactly how much lint on each thread too. Keeping my kids microscope was a great idea.

Its for long arm quilters.
