The drapery and rods were custom from Prestige Decor in Mississauga. They specialize in window treatments and handled the ordering of the rods based on my measurements. The rods were apparently the longest they could order and just fit the 10x11 pergola space! For installations larger than that I have used a track system rather than a rod that can be made much longer and look great with a ripple fold drape! You can contact Prestige at 905-566-5063 or take this info to your local drapery specialist and I am sure they can figure out the right solution for you. I hope this helps-NR
