A few years ago I was in my local quilt store shopping for thread. I had always used a certain brand and had always bought it from her. But on this day the shop owner started talking to me about what makes some thread better. I must have stood there talking to her for over 20 minutes on the virtues of good thread and in those minutes I learned that long cotton fibers make for better, stronger, easier to work with thread.
I bought a spool of Aurifil thread that day and haven't bought another kind since. Those longer cotton fibers make a difference. My thread rarely breaks while sewing. My needle and presser foot don't fill up with lint. And my bobbin case doesn't need cleaning as often. Plus, this thread doesn't get twisted in my machine and hand sewing with it is a dream.
I posted a picture of my newest Aurifil thread over on Instagram on Monday and it generated a bit of conversation. Come to find out I'm not the only devoted user and though I use 50 weight gray and white Aurifil thread exclusively, these variegated threads are making me reconsider that as well.
