We have curtains everywhere in the house, except the kitchen. There, it's a 1 1/2" or 2" horizontal blind.
The curtains in the bedroom and the living room always have fur and dust all over them. It seems I'm forever taking a roller to them, and washing more than I would like.
The curtains in the dining room, where my frame is set up are tied in knots - two knots per side because they dangle into the cords for the frame and generally get in the way.
The curtains in the sewing room are constantly full of threads, fur and dust.
The blinds in the kitchen need a quick wipe from time to time, mostly when food gets on then (they're over the sink). They're heavy, yes, but not often raised or lowered.
