Ok, I know this subject has been brought up before, but I want to make my own prefilled bobbins. I prefer 60 wt thread. BUT, have heard that 50wt is better. This is for regular cotton fabric piecing, NOT for embroidery work!

What is the verdict, 50wt or 60wt? My color choices are only beige, light gray, black and white! So thinking gray and beige will be best!

i use poly emb thread top and bobbin with no problems. seems lay flatter and no bulk. i wind at least 10 bobbins at a time.

My favorite thread for piecing is Aurifil 50wt (which is a 2-ply thread). I used to use Mettler silk-finish 60wt (3-ply). I like that the Aurifil is much less linty than the Mettler, and also that seams lie flatter after I iron.

I had never heard that 50 wt is better than 60. 60 wt will obviously be a finer thread and if that is what you prefer to work with I would go for it.

I use 40 wt, top and bottom; I like the way the stitches lay. But "Ellie" (Babylock Ellegante) likes and adapts well with all. I have used 40 or 50 wt for top thread and 60 wt for bobbin, no problems at all.

I use Aurifil (low lint) 50wt top and bobbin for piecing.
I have white, black and gray and wind multiple bobbins.
I store thread with its bobbins in an old prescription bottle.
This contains tangles and keeps it separate from other thread.

I have Aurifil for the top, 50wt!
My next question is, 2 ply or 3?

50 wt. is a heavier and stronger thread than 60 wt. And it's the reason I use it for piecing. 60 wt. would be better suited for finer stitching like heirloom or in the bobbin for embroidery.

ditto

they are recommending the 60wt for paper piecing now and I do a lot of that, but if 50 is best for everyday stuff, I might just have to use that!
