I finally found a fabric I like to make a valance for my kitchen sink window and carport door half window. The only problem is that it is indoor-outdoor fabric. Will that work? Will it look too stiff and flat? I'm planning on using a 2-inch rod pocket. If I could use it, do I need to line it with drapery lining? Here are the links to the fabric and pattern I am considering, both of which go off sale tomorrow at the nearest Hancock's about an hour away, so it's now or never on this choice. They also have a stripe that might coordinate, but I need to look at it again in better lighting. Should I just keep looking? I'm having the new in-laws-to-be here in January and wanted to finish the kitchen by then; so I don't really have time to order swatches. If you have any suggestions of where to find similar fabric that is not indoor-outdoor, please let me know that as well.
Thanks, this has driven me crazy for over a year.
