Ok so I pieced more than half of a full size quilt using the Craftsy thread and I have to say I like it. I'll try to include some photos of the threads side by side. The color of Aurifil is 2310 which I ordered a cone of and that is what they sent this spool of Craftsy thread with. I assume they were trying to match them and it isn't a bad match though they are different. The Craftsy thread is Parchment just for reference. Here is what I did and the results...

1. I cleaned out my machine to get rid of any existing lint so I could truly compare threads. The Craftsy thread did produce significantly less lint but it is not "no lint".
2. To feel the threads between your fingers the Craftsy thread is smoother to the touch than Aurifil.
3. Compare them side by side the thickness is the same and to the naked eye the Craftsy thread is slightly smoother.
4. I did not have to adjust either the top or bottom tension when switching from Aurifil to Craftsy and both produces beautiful stitches.
5. My machine isn't finicky with threads so that wasn't an issue that I can report on perhaps someone else who has a finicky machine can give some input.
6. Perhaps it is just the color difference but the Craftsy thread seems to have a sheen to it that Aurifil does not.

The strange thing for me is that right now the price difference is tiny when you break it down by the yard.
Aurifil $8.24 for 1422 yards = .579 per 100 yards
Craftsy $7.00 for 1200 yards = .583 per 100 yards

If my memory serves me well I think Aurifil is typically $10.40/spool but there is a big sale this weekend. I will be curious to see what the normal prices are for both threads.

Will I buy it in the future? Sure. Will I stop buying Aurifil? Probably not. This is all just my opinion but I hope this helps others. Can't seem to upload photos...sorry about that.

I ordered some today and also ordered a kit. I'll let you know how I like it.
I need a kit like a hole in the head :D

I got mine today. I have a microscope so I will compare Crafty thread to Aurifil under magnification. That's the real truth. Some threads look like barb wire under the microscope!

LOL I needed thread like that too. Had to try it though.

Yes, mine was complete spool as well.
christina 223, that was a great comparison. Thank you.
I wonder if Craftsy will offer their thread on sale more than Aurifil?

And to the above postr about free shipping, thanks for the reminder. i have Unlimited too and I didn’t realize shipping is free! Awesome.

I think the free shipping was offered when it Unlimited was first available. Now it's a free gift card if you sign up. Check to see which benefit you received when you signed up.

I signed up for unlimited a few weeks ago. The offer was $100 in gift cards ($25 each quarter) and free shipping with annual membership that cost $120. It was a deal I couldn’t pass up since I really enjoy their classes.

I tried my spool of thread yesterday and love it. It worked fine in my machine and loved binding my quilt with it. I will buy more for sure.

I joined Craftsy Unlimited and I was given 1-free quilt kit up to $185 (Choice or 3different kits) and $25.00 in notions and I received a spool of Prima with each order, plus the 40% off coupon with entire Prima order. I have not tried it yet but it feels wonderful.

I used it this last weekend. It sews the same as Aurifil and Masterpiece to me. I used it on my Bernina and my Brother machine.

I received two spools free with 2 different orders and I really like it. Doesn’t have much lint at all.
