I had never seen this style of blinds before. We recently remodeled our kitchen and wanted something other than cheap vinyl slat blinds to cover the sliding glass doors that exit to our patio. These are perfect, especially once added a short tight top valence to tie it 100 to the room. They slide smoothly and can open  either direction which was fantastic especially for floor and glass cleaning. I’ll be ordering these for some other places in our home soon.
