I use Robinson Anton Rayon thread and it is the best I have found so far. It dosen't break like so many of the others I tried and it has a very nice even finish
Would love to hear from others
Regards Dixie

I use Sulky. My DH bought me a box w/ 8 dozen spools when I got my embroidery machine and I love the way it shines. Some of the other brands are making theirs more polished looking. I know that the people who sell my machine (Bernina) reccommend Mettler. They say that it can be bleached and Sulky can't. I don't find the need to bleach very often, so it doesn't bother me.I also can buy Sulky in bulk spools wholesale.

I have to admit that I have a bit of almost everything. I like the Isocord, although it is a touch pricy (unless you get it on sale). I have a bunch of Sulky, some Robinson Anton, Mettler, Belding, Coats and Clark, Poly-Sheen, Talon, Corticelli, and a bunch that is unlabled that I got from a commercial embroidery company when it closed. I sometimes think that I may never have to purchase thread again! And then I find a project that needs a color that I somehow don't yet have, and so I buy some more. =]

My preference is for Sulky then Robson Anton depending on the shade I need and which company I am ordering from. I certainly keep away from Madeira which is not embroidery friendly.

I use Marathon. I love the way that it stitches out. I have very little thread breakage. It also is much cheaper than all the others.It washes very well and has great shine to it(poly)they also have rayon,varg,metallics. Very Good.
