Decision made! I will sew on matching fabric to the tweener tris, I did a few last night and after they are pressed I am satisfied! Most of my fabrics are small print so that helps disguise the seam. I have a pack of triangles in my fabric line, so I have all the fabrics!
I don't know why I go blank and can't see the "forest for the trees" with color choices on this quilt! I think it has become a bit emotional since it has such an large investment of time and effort.
Thank you ladies for all your input!
