I ended up getting four skeins of Shimmer in Bayou and two skeins each of Shadow in Snorkel Heather and Spring Green Heather. Here’s my swatch:

I held one strand of Bayou with one strand of Snorkel for the first half, then switched to one strand of Bayou with one strand of Spring Green. Using Bayou throughout softened the other two colors and pulled them together nicely. I got gauge (20 stitches/4″) using size 6 needles, then washed my swatch in cold water with some Kookaburra and blocked it out on a towel to dry overnight. The fabric softened up quite a bit after washing, and the Shadow kind of puffed up a bit and filled in the gaps in the fabric. <
