The drapery thing you were talking about sounds like some kind of a cornice/decorative top piece made of rigid material. MrT5 made cornices for the kitchen windows, but they are decorative wood-no fabric-so they can be easily cleaned-I had the fabric covered ones at my other house, and they were a bitch to keep dusted.
I love wooden cornices, and drew a plan for one made of fancy 1/4 in. plywood with a pattern of leaves cut out with my jigsaw and dremel tool-it didn’t fit the masculine décor here, but I will make it this next time around...
that sounds lovely. yes this is somehow mounted to something. The woman who cleans them is very detail oriented and did a fantastic job of cleaning them. having zero patience, i’m pretty sure i would hurl them into the trash if i had that job!
