Well feather and fan fits your description of a pattern row then plain rows, but it can be tricky even though it's fairly simple.
Try the Clapotis
. It's basically stockinette, has increases or decs at the ends of the rows because it's knit on the diagonal, but you get to drop some stitches for a really cool effect, especially in yarn with long color changes. It's kind of a shawl, but you can do less of the repeats in the increase section to make a scarf.
