How can I create this moire pattern in Illustrator?

Question

How can I create this pattern? I need the white lines to be paths.

Using Illustrator, I created the wave, duplicated it and then use the blend tool to create this. Then I duplicate the pattern.

And then I rotated the whole thing to get this:

But I want the spacings to be consistent like the original image I've posted. Any idea how to go about doing that?

Create a mesh envelope (Object â†’ Envelope Distort â†’ Make with Mesh...) with an even and equal number of rows and columns.

Select alternating columns of mesh anchor points using the Direct Selection Tool (A) and offset their position.

Create a pattern (Object â†’ Pattern â†’ Make) and adjust the height and width of the pattern to that of your original grid to align the pattern.

Finished pattern:

This was a quick example so it's not perfect. Some of the lines don't align perfectly but that can easily be fixed with a bit more time and effort.
