It depends on the diaper. On prefolds and flats, sometimes, there's colored thread on the edges, to prevent fraying. I think that colored, serged edges, and all that fluff, are, oddly enough, cute. Occasionally, you can find printed ones, but, why buy the printed prefolds, if you're gonna cover them up with a cover? As far as covers, girly colors, and, I'm ridiculously specific about print scale, and the type of print, and, OMG, the way it goes on my body, and the leg gussets, along with just about everything else about my diapies.:lol: That's why I'm a clothie. If you want something made perfectly, you gotta start from scratch.
