Thanks... there is a single increase to 119 stitches on row 5. That makes for 17x7, which is 119, so it does even out quickly. The 17th block on rows 1-4 are grey, which means "no stitch."
I should just jump in. The instructions for the first four rows are pretty basic, like knit or purl all stitches, so I won't have any disasters without the math working out in my head.
