Update- well I cut and sewed the sashing and the white on white is a slightly different colour then the backgrounds. I thought it was all the same dye lot but apparently NOT! I also discovered I have one W on W piece in the block wrong side up, sigh. The shower is coming up and I have to continue rather then rip it apart. I still have to get it quilted and bound and hopefully this will be the end of my ill fortune on this baby quilt.
