When are unlined curtains ok?
I know some curtains hang better if they're lined. And if you need to block out all light, of course you need a lining. When else is lining necessary?
I have some windows that will have curtains hanging over cheapo vinyl roller shades (possibly upgraded in the future to wood blinds) -- do the curtains still need to be lined? If I close them occasionally while the shades are still up, will they look bad from the outside (or the inside)? I don't want to spend more on lined curtains if it's not necessary, but I also don't want to spend time and money on curtains that look bad because I skipped the lining. Help!
