I just got the information by one of our wholesalers that they start to offer two brands of hand quilting thread by Superior Threads: Treasure and Perfect Quilter.

Has anyone of you already used them? What is your experience?

I love Superior Threads, especially King Tut varigated. Their pre-wound bobbins are great as well.

Superior threads are very good. I ordered the new silk thread from their website before it went to retailers. It was priced special to customers before the stores got it. Superior has a facbook page with lot of information about sales and new products. Lots of videos too.

If you go to Bob Purcell's website and click on those threads he'll give you alot of info on their intended uses and recommended needles.

I've not used these two, but love all his thread that I have used: Bottom Line, Masterpiece, Silk, King Tut and more
