I have completed the garter section and chose to do the 265 stitches instead of 229 as recommended by lala from the knitgirllls. This has worked well so far as the skein I have has around 500m. Very generous.
I plan to extend the feather and fan portion too if I need to as I want to use as much yarn as possible. As it is now, the rows are so long. So unbelievably long! But that's ok, because I'm loving the color repeats they really are beautiful.
