Thank all of you for your ideas. I went back and found that I needed 10 more blocks so that I could center the block with the black. I only have one of them. I intend to stitch around each butterfly with black thread to make it pop ----I hope.I was thinking of quilting it with the pattern with black thread. In other words outlining each butterfly with black as a quilting design. I intend to use the colors of green that I have and then since this will be a king size, put a border around it. Since I have left overs of each color butterfly, do you think a border of blocks of each one like strips would work? The colors don't stand out much in the picture, but they are bright.
