Ok, may seem like a lot of effort for little result, but I'm much happier now that I've re-put together the top. I'm still considering border treatments, but I think I'm probably going to go with something like this picture.
I really like the way the original designer used some geese units in the borders. But I'm almost out of the red with white pin dot, I have just enough to make 4 sets of the goose units, I could put one set each side of two diagonal corners. I am totally out of the cherry blossom background fabric, I'd have to use solid black.
I have lots of the large scale cherry and the gingham left, should be enough for the back if I piece both together in addition to the border. I have just enough of the white with red dot to do the double row as shown, or I can do one row of it and make binding with the rest.
