So here it is:
I love the way the flowers start out just a few at the top and get thicker at the bottom. But see the horizontal seam in the first photo? The fabric wasn't wide enough for the curtain and I didn't have enough for a second strip of this lovely border print. So I found an old white cotton sheet and pieced that for the top half of the curtain. Then (and this is the part I love), I used some fabric paints I had on hand to paint the sheet part with pink and green and turquoise flowers so it looks like part of the same shower of flowers.
