Thank you all for the information and the video link. I went into total brain freeze thinking about this. I have about 7 more squares to do and then I can start cutting for the sashing. Didn't want to cut before I figured out what was the best way to tackle this.

The background color is a light blue with each star being different shades of yellow designs (hubby loves yellow). I'm not sure yet if the sashing should be the light blue (same as background) or go with a solid lemony yellow so maybe need to go to the fabric store and get a couple of samples to compare. Then I can contemplate the outer border color as a yellow solid or print.

I'm sure I'll be back for more help and opinions and will post pics as I progress. Many, many thanks for all the help.
