I think that this pattern looks like poorly drawn tic-tac-toe boards (octothorpes). The yarns are the same as in mosaic 19: the navy is from Kim Dyes Yarn, colorway: String Theory-blue, yarn: sourdough sock, and the tweedy white is from Yankee Dyer Yarns, colorway: In the buff, yarn: yankee tweed. This pair is pretty standard-striped bottoms, pattern on the top. Nothing particularly new, other than the mosaic itself. I do like having a bit of variation in the stripe width though, particularly when there is so much contrast between the two yarns.
