Superior is the best as far as I am concerned-use it in my Bernina, Janome and Brother machines?

I have a Janome 6600 and my absolute go to thread is Aurifil, my machine loves it! It seems a bit pricey, but really does seem to last forever.

I've used Aurifil for several years and love it.

I am a Superior junkie too. The only time I buy something else is if I absolutely need a small amount of a color then I get a small spool at Joanns. I love So Fine, MonoPoly, Magnifico for machine embroidery, Bottom Line or embroidery bobbins. The list goes one. Since I am mainly a quilter doing lots of piecing, i pretty much stick to cones of white, off white, black and grey. .aunrifil is a good thread butprefer the poly on large cones. Superior.has a huge variety ofm threads and has so many specials. Superiorthreads.com

I buy aurifil on ebay. The last time was from a shop called Crazyquiltgirl fabric shop.

I have Pfaffs, a Brother and had a Janome. I use Aurefil 50/2 (orange cone). For piecing I like it the best of any threads I have tried.
