Edges...

I'm trying to figure out how/where to stop on my Tangerine Tango EPP top. image

not the side, just the edges....

In theory, every hex should have a square on each side, and then triangles to fill the gaps...

If I only do completed hexies, though, 2 of the sides have these hugely uneven edges:

and since the other two edges look so cool, I'm just not sure what to do.

So maybe I need to add in the squares, and then cut them into right triangles to make a straight edge on those sides?

 

Thoughts?
