I'm hoping someone out there can help me out with a drapery question. I have a cornice box and underneath it is a traverse rod where my draperies will be. Unfortunately I miscalculated the measurements and my drapes are 2 1/2 inches too short. I already placed the pins/hooks as high as they can go on the drapes so my question is, (without having to lower the rods (which is doable), is there anything I can add like an extension ring or hook to the holes in the traverse rod so that it is 2 /12 inches lower? I hate to go to the trouble of removing the cornice boxes AND rods. Hoping there is a solution here.
