Here I'm working with a 7x7 block grid. The red marks tell me where the grid will be interrupted and the light pencil markings are the beginning of the knotwork. (You'll see an oops in the picture here, where I didn't highlight one of my "stop marks")In the next pictures you see how I'm working my way out of the center.With some lines I stop to take a moment to see where the lines will lead me.And then I can continue to close the lines. By now this looks pretty confusing, don't you think? To make the visualization easier on me I decided to use different color highlighters. Later on, if I decide to turn this into an actual project I can use different colors of fabric in place of the different colors of highlighter that I used, or make the design all in one color, but I think different colors make the projects more interesting.Here you see more clearly that some parts of the design are continuous and others (although continuous in themselves) are not continuous throughout the entire design.
Now it's time to fill some of the empty spaces, shown with the orange highlighter - and you probably can see that something's still missing.So to balance the design out, I mirror image the orange line and fill the rest of the design in with the yellow highlighter.
