If I'm using my snappi (which I couldn't live without) I use the bikini twist. It's the only way that I have found to fold it that makes it nice and trim, and tight fitting. When I just use a cover and no snappi, I just do the normal tri-fold. I really prefer using the snappi because it isn't so bulky and it stays in place. I use whatever cover I have. My Kushies covers work quite well, but really all of my covers seem to work fine with my prefolds. Hope you can make it work.
