I do not like this, Wilted-quilt
I do not like this on a train
I do not like this in the rain
I do not like it in the snow
I would not quilt a tic-tac-toe
I will eventually post a photo showing all of the blocks together. It will then become obvious that this square stands out like a sore thumb. Look at the photo of Marti Michell's quilt in 2104 BOM - Secret Garden (January 2014) to get a better idea. Hers is actually not as bad because she has more uniformity of color to tie the blocks together, and the crossbars tie in nicely with the sashing. That will not happen with my quilt top because the sashing is green and dark gray.
Lessons learned:
1) If you don't like a block, why not substitute another block?
2) Over-substitution of fabrics might solve one problem, but can create another problem when the squares don't have enough in common.
