Since you are fairly new, why not do something fairly easy (save difficult for when you gain confidence). Using a walking foot you can easily do a wide wavy line down the red sashing. If you like that look, you could then do another wavy line down the center of the blocks. Doing this allows you to gently 'swerve' the top rather than make turns. Another idea would be the waves in the red and then do a square within the block. Make it just inside the blue seam so it is a bit less than half size of the block. I am not a fan of stitch in the ditch nor of heavy all over quilting. And I think this would be adequate to hold everything together and not make you crazy!!
