Variations on a half-square triangle quilt layout

I've been piecing up a big pile of half-square triangles (or HSTs) for the last few days so I thought I would play around with some layout options just for fun. 

 

(Same camera, each photo just minutes apart, same time of day, and look at the color variations)

I pulled teals/aquas and added a pop of rust red/ brick orange later.

I like this one....

let's add the accent colors...

Yup, that's nice.    A little small though, let's add a row at the side and bottom....

 Nope, now the center square is too far up.

And maybe a little play on the design just a little....

That's better! 

Now, off to stitching the rows together!
