I got these vertical blinds free and after cutting this one down to size and reassembling it, and thinking I hated the fabric slats, realized I REALLY hated the fabric. (it looks like my doctor's office...) Sooo...what about if I do this? (see below) birch slats to match the ceiling? maybe rip some edge "C" trim to cover the edges out of walnut? that should help keep them from warping too, yes? then the birch/walnut curtains will REALLY match the ceiling!!! opinions?
