Here are links to a couple I made:
This one is made with Lovely as a Tree and could be used as Sympathy card:

This one is made with a brass stencil and a stipple brush:

I also think that you could use a floral one, like Easy Elegance or Watercolor Garden. Do it in black and white--do the flower in black ink on white paper, then use some kind of black and white BG. I don't have any examples, but I have seen some in the galleries. Keep the colors muted--B&W, or browns and golds. Don't use ribbon, or use twill or something muted, not shiney or filly (no orgundy.)
Those are my suggestions. Hope that helps.
