I've been using Superior threads for many years. I like and use So-Fine thread in my bobbins for my embroidery machine, in my sewing machine bobbin when doing applique, and also in the quilting machine. The thread is lint free and strong.

I was having trouble with my thread breaking or slipping in my Singer sewing machine. I tried this thread and it works SO good, Since I started using this thread, I have not had any issues with my sewing which is a God send for me.

3 ply thin strong thread. I like it for free motion quilting and piecing.

I'm using this thread for quilting with a domestic machine and hand sewing the quilt binding. The Silver color (408) I ordered is a medium gray and blends well with many fabrics. It's just a bit lighter than pictured as I guessed it would be. So far I am very pleased with it.

Superior threads makes nice thread. My only issue with this thread was the color. It comes off as more orange red than red. Really hard to know this when you order online.

This thread is the best I have found for my longarm quilting machine. It is really smooth in the machine and doesn't break like some other threads I have used.

The mushroom color works with almost any color of fabric. The 50 weight is thick enough to use for quilting.

Superior thread, indeed. It is smooth and virtually lint free. I like this thread so much that it will likely be my go to for everything, from quilting to lingerie sewing.
