Seamless Tiling Background Challenge

[Acorn]

Gary, I had to tweak your design.

The basic pattern unit is:

I made this with 4px, 64px & 4px boxes, grouped and Skewed to give sharp edges.
Copies were coloured and rotated.

The repeat can simply be slid in place across and down.
I centred the shapes so the inner empty hexagon and triangles were all balanced.

My design file is: SVG - Gary's Mesh.xar

The SVG as attached separately.
