Diamond Quilt-Almost Done

I am still working on my Diamond Quilt.
I am almost finished.
Only 2 more long seams to sew.

This is the brown corner.

This is the black corner.

This is the green corner.

And this is the pink corner.

And this is my only oops! Out of 672 HST's.
Two triangles of the same fabric touching each other.
I have one seam ripped out in this picture.
Three to go and then I will put a different HST in it's place.

Call me way too particular!!
