Most fabrics nd home decorating retail stores would have them.

Look on etsy

I'm really liking some linen/cotton panels I found on pottery barn, but I want to see other options before I plunk down $450 on 4 panels. I currently have dupioni silk curtains and I think they are too shiny for my great room, which I am working to make a little more light and casual. I need to have them lined also.

These are the style I like thus far if you have any other suggestions. I have a swatch and its very pretty.

I'm repainting the great room (it is currently dark taupe) SW Accessible Beige @ 150%, and my plan is to replace my darker taupe silk curtains in the process with some lighter gray and cream ones.

Also I do not have much for home décor stores in my area, no pottery barn, west elm, ikea, etc. so I've been looking online especially since I require the longer length panels...thanks for suggestions!
