Your blocks are beautiful and I love anything flowery. That said, I would finish piecing the top with borders first and look at it again. you may find with all the colors in the baskets that the flowers are really kind of lost and all the work of applique and your great piece work will be lost if the overall top is too busy. Remember too you will have quilting too which will fill the now blank spots that are white. I like the idea of putting flowers in the border though I might only cluster a bouquet in one corner or the middle of the bottom border if you cannot stand asymetrical design. Will it be a wall hanging, bed quilt or throw quilt?
