Inside rod might not be long enough, weird. The BlockAide window curtain rod combines elegant style with function. Its wrap-around design allows window curtains to return to the wall to block side light from entering the room and provide privacy.
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!
