Or Paint or Stencil on them with Fabric Paint. Or Sew or Stick or paint Motifs on them.. or Buttons or anything else that you fancy.

Consider light weight balances in a coordinated color, but different pattern. Perhaps adding ribbon either vertically, or perhaps seeing a band of different color horizontall?

You can fancy them up by adding various widths of ribbons to them using seam tape or sewing them on in a vertical or horizontal design. You can also paint a design on them using acrylic paint mixed with water and a fabric paint solution that can be purchased at Michaels or JoAnns or Hobby Lobby. You can also apply another fabric onto the plain curtains to create some visual interest.
