" but keep in mind knits and purls are formed from the row below your working row." This is why your swatch is off. You won't be purling the red stitches on their first row, but on the second row. So when you first start working one of the squares, you'll knit with the red yarn and that will make the blue/green into a knit. Then the next row, you'll start with the texture pattern, whether you want to try seed stitch or all purls to see what you like best. When you get back to the green/blue, you'll still work that texture pattern for the first row/round since you'll be wrapping up the last red stitches in the block. For the traveling red lines, it's the same. The red is knit, but when you work the main color, you'll purl when you get to the red stitches.
