Spinning for Color

I finally wound my first 50 grams of plied yarn for Color Affection into a skein.

I'm very happy with the look and feel of the yarn.  I was aiming to match Knit picks Palette, because others had used that for the Color Affection successfully.  50 g of Palette has 231 yards.  My skein came in at 258 yards.  Whoohoo!

Now here's the problem.  I've looked at a lot of finished projects on Ravelry that used the Palette Yarn, and almost all of them used more yarn than I just spun.  What did I look at before?  I know it was weight, not length.  I'm wondering if I need to add fiber to one of my other chunks to make more yarn.  Trying to make it come out just perfect seems like a recipe for disaster.
