I like the variegaed theads, myself. It lends a nice touch, sort of like another layer of color to the whole project. If you go to all that trouble,you want the qulting to show. Sometime,when stitching in the ditch, I have to turn it over to the other side just to make sure that I've stitchd everwhere I was suppose to. Sometimes with invisible thread, you can't tell, because its too hard to see it.
