The rectangles on that quilt finish at 2x5 -- guess I started with 5.5inch squares.
The sashing is all the same color as the border, cut at 1.5, finished at 1 inch (so the rectangles and sash make a 5 inch finished square).
If you start with 6.5 inch squares, you'd just cut them one way down the middle for 3.25x6.5 inch rectangles, add 1.5 inch sashing and you'd finish with a 6 inch block. I think. :? Its early and my mind is not awake yet. :lol:

I freehand quilted swirls in each block. It was a lot of fun to make, and Leith really likes it.
