I got some cotton fabric with big red flowers to make curtains for my living room. I don't really want to line them cuz I like the weight and drape as it is. Is there any way to slow down the sun fading? My previous ones faded over a period of years and I'd like to keep these nice as long as possible. I've been reading about stuff that you can spray on fabric. Has anyone ever used it for inside? (I'd like to hear out side experiences too actually as I'm thinking my porch cushions could use some protection.) Any other suggestions?

btw my "curtains" are rather unconventional. We don't really like to hide our windows but want the option of privacy so I just sew a big rectangle to cover the bottom half of the windows, attach rings to the 2 top corners and stretch them across the window between 2 cup hooks. I have one cup hook higher up on one side to hang the other corner from when not covering the window. Our windows are double so we have one "curtain" hanging on each side. Just don't tell the HD forum, lol.
