Bobbin thread
 

What do use for bobbin thread when piecing?

Same thing as I use for top thread.

Bottom line from Superior Threads, or what ever I have handy. ( often Aurifil or cotton thread from Connecting Threads)

I use Precencia 60 weight for piecing and the same in the bobbin. You don't know which way you are going to press the seam when you sew the patch, so I like the thin thread on both sides.

I use whatever I have. Right now its a YLI thread which I think might be 50wt. Came with my quilt machine. I use bottom line in my embroidery machine when embroidering as its 60wt. Machine didn't care for NEB's bobbin thread so keeping them for the other machine that don't seem to care what I put in them.

I use what I have on hand which is C &C. Coats and Clark.

I try using same as top thread when piecing. I find it easier to "pick apart" mistakes when I have same bobbin thread. During FMQ I use Bottom Line, because the bobbin lasts a whole lot longer. And then I hope no "reverse sewing" will be needed!!

Me, too. :)

Same as the top thread which is usually Aurifil.

Bottom Line. Fewer bobbin changes and my piecing is more accurate. (I like paper piecing, miniatures, and complicated tops.)

Lately neither of my machines do not like the Bottom Line thread - it has thrown off the tension something fierce. (One is Viking Topaz Sewing/Embroidery machine and the other is Janome MC6600P.) So now I use the same thread for both the top and the bobbin.

I had accumulated quite a bit of Coats and Clark over the years sewing that is still good but my machine doesn't like it very well - shreds and breaks - but works fine for the bobbin. I've been taking and filling bobbins with that and using it up. I have never seemed to have issues with getting a good 1/4" seam and everything fits together just fine so I go with it. Most any color will work for me since you don't see it anyway. When that thread gets used up I'll probably be more picky.

I like Connecting Threads Essential Pro Polyester. It's super fine (70 weight) and strong. I use it to quilt on my Gammill, too.

I use the same top and bottom, and none of my machines are fussy most of the time I use the Coats and Clark (I know, it is poor quality and turns out to be expensive) but I can get it in a lot of colors and not have a bunch of it sitting around when I am done. So that is my go to. I do have aurifil that I use for piecing sometimes. I have used sulky variegated for FMQ and that works okay.

Bottom Line by Superior in top & bobbin. I use it on my dsm & in the bobbin on my George sit-down quilting machine in the bobbin. Have never had any problems with either machine & I like the 60 wt because of the thinness of the seams. I use mostly neutrals for all my piecing but will match the top thread when quilting on George.

I use CT Pro for piecing and bobbin. I have a lot of Aurifil, Finishing Touch, Bottom Line, and Sew Fine I use. I like the Masterpiece pre wound bobbins too. I don't really care what brand as long as it's very good thread. I gave away all the C&C thread I had. It was older so the new version may be better. I know C&C cost more per spool for less yardage then the other brands. You are not getting a bargain.

I use the same thread in the top of the machine as I have in the bobbin-Aurifil. Love this thread.

Another Aurifil devotee here - I use 50 wt. top and bottom for piecing. Never disappointed!

Superior Threads Masterpiece, top and bottom. Strong, fine and pre-wound bobbins. Look for the sales.
