I purchased two panels of this gorgeous curtain for my master bedroom patio door. Absolutely love the look of the light and airiness and knowing the lined panels will also help save on heating and air conditioning loss. They hang beautifully and have an elegant look to complete my bedroom makeover. I compared prices on similar panels and this seems to be a great value for the quality of product. I would recommend this curtain for those of you who are sitting on the fence about it. Of course the winter weather has passed, I am looking forward to next winter to actually determine how they do actually help prevent heat loss and keep cold air out.
