Now no matter what I do in the sewing room, I know I can grab the Isacord thread and use it for everything, from embroidery to piecing to quilting. Good strong, beautiful, silky smooth thread, and one of the lower priced threads available. I have not used King Tut, Superior, Connecting Threads, so I cannot vouch for those.
Bottom line, I broke away from rayon and headed to polyester for embroidery. The Isacord is high sheen just like Sulky and rayon embroidery threads. Makes for beautiful quilting and embroidery.
I do not work for Isacord, I am not a retailer, etc. of this thread. I simply have found a very good high quality thread that I personally can use for everything.
