Replace your curtain rods with swing arm rods to open up the room and allow more light in. Windows appear to be bigger than they are, too. Love swing arm curtain rods, I have been on the hunt for old ones for a long time.
Ribbon CURTAIN for a lil girls room! Cut ribbons double the window's length. fold in and loop around the curtain rod! I would put a solid color curtain up, and a separate rod with that lace ribbon stuff.like, pink curtain with white lace ribbon.
Attach a sheer curtain panel behind your existing curtains using a bungee cord. Just run the cord through your curtains, attach the bungee hooks to the sides of the rod and stretch it across, and voilà, you have a beautiful sheer inner curtain panel!
