Feather and fan is really easy, and comes out looking like it was complicated! Basically you cast on a multiple of 18 stitches (I would put markers in between each set of 18), do a couple of rows of garter just for a border, then:
3) (k2tog) 3 times, (yo, k1) 6 times, (k2tog) 3 times [repeat for each set of 18 stitches]
And repeat till it's long enough. The 4th row will be a garter row, and really makes the pattern pop.
