I think the most important thing for this one is that, once you've got the base structure complete (step 3 in step-out instructions), that you continue to work in the same order i.e. strokes on all of the front grid, then work on the back grid, then repeat till happy with the result.
Here's one showing the pattern drawn freeform - this is a speed-draw video - 8x speed. It's done using the same base structure but without the dots. I also add on where I feel I need more, so it's not as methodical.
Have a great weekend!
