Recreate.
Example: Make sure you have windowsills.
Get frilly curtains, you know, those ones that're lacy with holes that make designs and such? They need to reach your windowsill.
Get a long planter that fits on your windowsill lengthwise, and plant any old plant like grass (I think grass works among the best, and cause it's cheap to get seeds).
Put the planter on top of the overhanging curtain. What'll happen? As the grass grows, it'll entwine all throughout the curtain, and look really neat.

Not too great of an example, but it gives you the idea. Something I'd do. <.<
