It's hung with ibeam, which is an inexpensive way. It's generally white and has glides on it to hook the pleats into. We buy in long lengths and get installer to cut down. You may be able to get it at Home Depot? Never looked for it there but most window covering stores in your area will have it. :)

Many thanks...I also see that you posted photos using Tekno wavedrape hardware. I also like the "no ring" look with the decorative rod and think that this may even be better for my application. Thanks for your advice!
