That’s right. Most of the lace panel for these patterns are made up of two parts—yarnovers, and a centered-double decrease, abbreviated CDD. Take a look.
I went through and highlighted all of the yarnover, CDD, yarnover sections that stand on their own throughout the pattern. Here’s a close-up of the sequence. We’re working the second row from the bottom, going from right to left (because it’s a right-side row), so you knit 1, yarnover, CDD, yarnover, knit 1.
But you’re not just working this sequence on its own. If I go through and highlight every single instance of a “yarnover, CDD, yarnover” combination…
The whole chart fills in with highlighter (in this instance, I was highlighting other combinations as that helps me to visualize the chart a little bit better).
Since this combination is pretty important to the chart as a whole, I filmed a video demonstrating how to work. If you’re working the Marsh pattern, you technically work the front first but could easily switch to working the back first. If you’re working Mallow, you will be working the back first.
