I don't think it will matter in the end with all those scraps involved. No one will even notice. That being said, I like A better but that fabric right side looks closer to sort of "matching" the piece two places below it in B .... assuming the photo is fairly true to the fabric colors. Again in the long run, it probablly won't matter.
Do you cut those fabric bars on an angle just the way they look in the block and carefully sew them together or do you have another method of piecing these blocks? I do love the look of your blocks!
