I assume you want to do it as a disappearing nine patch, right? I'm posting from my phone, so I can't draw a picture, but here would be the process:
Make a 9p with a plus-sign of light blue (or yellow), and the peach (or navy or print) in the corners. Cut as usual.
Personally, I would use strip piecing instead. Join a 2.5 inch WOF strip of light blue (or yellow) to a 5 inch strip of peach (or navy or print). Cut into 5 inch sections, and add a 7x2.5" strip of light blue (or yellow) to complete the block.
This quilt is an excellent example of how there are many ways to reach the same end result!
