I have a spool of YLI variagated that goes yellow to light orange. I got it as part of a class kit at the quilt store, and it is SO subtle, I kind of feel ripped off. I can see there are two-three colors on the spool, but when quilted, I CANNOT tell any difference at all. I want to at least see color change when I get variegated threads. I was majorly bummed when that was handed to me in the class.
