With shawls, size does matter; I like them huge. And I also like them in speckle-dyed yarn and garter stitch. The Striped Esjan pattern by Stephen West has some additional lace knitting besides the garter stitch, but nothing too complicated, and I love the enormous holes created by multiple yarn-overs.
I used a multitude of yarns, in part because I wanted to knit the larger size but didn't have enough of colors A and B. The speckled yarn is the Boombox colorway by Hedgehog Fibres in the Skinny Singles base, and I used the matching Crystal colorway in the Sock base as a solid counterpart for the garter stitch stripes. However, I didn't have enough of either yarn for the thin stripes between the lace sections, so I substituted with some Silver Fox by madelinetosh in merino light, which is close enough to Crystal in color, and then I used some Cephalopod Yarns Skinny Bugga! for the bright green color pops. I ended up doing an i-cord bind-off with the remaining speckled yarn, but there wasn't enough left for the entire bottom edge, so I mixed in some more Silver Fox, and they blend in so well you can't really tell most of the i-cord is actually these two bases striped. Oh, and the fuchsia lace sections are knit with Wollmeise Pure, so the finished project contains no fewer than five different yarn bases, but they play together quite well, I think.
