Thanks Macebaby!
I made another block with the dark blue fabric. Just a tiny 3" finished one so the fabric won't be noticed. I think I'm going to replace the dark blue in the large block. I'm quite sure I always will 'see' it and wonder why..........
I'm like you, impatient but for me without having any deadlines. Lately I'm learning to adjust things, replace pieces, resew seams......well you get it

. We're never too old to learn!!
