Gray quilt progress

Here's what I have so far.

I paired each charm pack square with a square of gray fabric, drew a line down the middle and sewed a quarter of an inch down either side.  Then I cut on the line, making a bunch of half square triangles.  
I decided to add gray strips to the half square triangles in order to make the block bigger, since I want it to be a lap sized quilt.  I also wanted my triangles sort of floating in the middle of the block.  Easy peasy!
