I kind of hope a yarn will flash or pool. I know this is an unpopular opinion; but when I look at a skein of handpainted yarn what I'm seeing is pools of color. So if I like the skein why wouldn't I want the piece knit up to look the same? Also, I know that I have an arsenal of tools under my belt to control the color placement in the final piece. Maybe other knitters would like to see that? Stockinette stitch does THIS, a slip stitch pattern does THAT, lace does something else entirely.
