I don't have winter/summer drapes, but I do change them up on occasion.
I have fairly heavy drapes that I layer with sheers. Underneath that I have wooden blinds. My cats have destroyed plastic mini blinds in the past by going behind them and coming back out, bending them back and forth.
In the winter I tie back the drapes and open or raise the blinds to let sunlight in during daytime. If a person had drafts they could get those beanbag type doorstoppers to put in the windowsill. At night they get untied and pulled closed.
In the summer they pretty much stay closed. If we want to see outside, we go out there. heh
In spring and autumn I take them down and open the windows on occasion, letting the breeze air out the house. I keep the drapes stored away until I'm ready to put them up again, and get them cleaned before I do.
