I have used Superior's water soluble thread. I was very happy with it. I've also heard good feedback about the Superior company.

I bought the 80 spool set of Thread Art on eBay. I like the sheen of it but I'm having thread breaks really bad. At first I thought it was my needle, tension, burrs...whatever. But I can change the thread with to another brand, same hooping, needle and tension, and have no problems.

Of course they say they've never had any complaints so I must be the only one!

I'm switching to Marathon.

I have used both Superior and ThreadArt thread. They both work well for me but I prefer ThreadArt thread. The prices are great and the colors are beautiful. I have not had any problems with breakage.

BTW- Superior thread does not fit directly on my sewing machine.

I too, use ThreadArt, best thread and prices, great shipping, wonderful colors, don't have any problem with thread breaking.
