My machine is a thread snob too...I found my tension has to be set on 8 and right now I'm trying YUI I think but I have another spool from the quilt store to try. It loves a German brand and I found big spools once and of course I can't find the big spools again only 250 meter ones of AMMAN or AMANN (I'm not in my sewing room). I even called the company to find where they supply it to I'll be making the trip.

I have heard this complaint before about this thread. My machine a Janome Kenmore uses most anything just fine. I have not tried Sulky.

I have great luck with Sew Fine on top and Bottom Line in the bobbin.

Thanks to the Viking users for weighing in. Have new to me viking rose lots of connecting thread threads and a brand new foot to try. Guess which configuration I am going to try first? Love this board for all the info on the quirks of various machines and techniques. I'm most interested in what will get the job done neatly and cleanly first shot if possible.

I use good old Coats & Clarks on my Babylock with no problems.

I use Presencia. It is a long staple Egyptian cotton which produces very little lint. The 500 yd spools are more cost effective than the smaller spools.

Connecting Threads Essential Cotton works great in my Bernina.

Lynda, I have been using the Superior also - sew Fine for bobbin and spool - for piecing and machine quilting on my Janome. My only problem is that it is SOOOO fine that I can't see the stitches to use a seam ripper on it! I had to make the stitch size bigger It is a lot easier to see Aurfil.

What is the advantage of using the Bottom Line? Would you use it for piecing also?

The Sulky I'm using is 100% cotton...I bought it at my LQS.

Thanks for all the advice everyone! :)

I just bought the thread from Connecting Threads but haven't tried it yet but I do love Aurifil on my Viking. The rep when I bought the mega quilter said Viking recommends this thread. I use it more than any other for everything. I'm trying Connecting Thread due to the cost. I also use Aurifil on my other Vikings with great success and low lint.
