Open Hexagons Stitch

So, in my last post,  I observed that there are hexagons in fabric made with stitch 00100.  I decided to diagram it and figure out how it would end up.  That diagram is pictured to the right.  Note that the written pattern had to be tweeked a bit when I actually worked the pattern.  That was merely the first draft, but I thought y'all might want to see it.  It occurred to me as I was working on this, that this is similar to filet crochet.  There is a grid where you can have holes or fill them in to create a pattern.  This is simply a different grid, made up out of triangles.  In this case, filled in means 3 dc, and holes are just a ch 2 and a dc.  Unlike traditional filet crochet, diagonal edges are inherent in the grid.  To make patterns this way, I'd recommend using a more precise grid than I did.

In any case, I tried out this pattern and this is the result:  It is a pretty solid fabric done this way.  It would be a simple matter to make the inverse of this pattern: filling in the holes, and opening up the solid portions.  That might make the hexagons more readily apparent. 

Here's the complete pattern:
Chain a multiple of 6 + 2
Row 1: sc in 2nd ch from hook, (sk 2, 5 dc in next ch, sk 2, sc) across
Row 2: ch 3, turn, 2 dc in first sc, sk 2, (sc in dc, ch 2, sk 2, dc in sc, ch 2 sk 2, sc, sk 2, 5 dc) across, 3 dc in last sc
Row 3: ch 1, turn, sc in dc, (sk 2, 3 dc in sc, ch 2 , sk 2, sc, ch 2, sk 2, 3 dc, sk 2, sc) across, sc in last dc
Row 4: repeat Row 2
Row 5: ch 1, turn, sc in dc, (sk 2, 5 dc in sc, sk 2, sc in dc) across, sc in last dc
Row 6: ch 3, turn, 2 dc in first sc, (sk 2, sc in dc, sk 2, 5 dc in sc, sk 2, sc in dc, ch 2, sk 2, dc in sc, ch 2) across, 3 dc in last sc
Row 7: ch 1, turn, sc in dc, sk 2, 5 dc in sc, (sk 2, sc in dc, sk 2, 3 dc in sc, ch 2, sk 2, sc in dc, ch 2, sk 2, 3 dc in sc) across, sc in last dc
Row 8 : repeat Row 6
Row 9: repeat Row 5

Repeat Rows 2-9 for pattern, ending with either row 5 or row 9.

Here's a simplification of the pattern:
Row 1: shell across

Row 2: (filled, open) across
Row 3: repeat Row 2
Row 4: repeat Row 2
Row 5: shell across
Row 6: filled, (filled, open) across
Row 7:  repeat Row 6

Row 8 : repeat Row 6
Row 9: repeat Row 5

Quick definitions
Filled means either (sc, 5 dc, sc) for even rows or (3 dc, sc, 3 dc) for odd rows
Open means either (sc, ch 2, dc, ch 2, sc) for even rows or (ch 2, sc, ch 2) for odd rows
Shell and Filled are the same
