Fabric Dilema

Over the weekend, I went around looking at fabric...for cushion covers and curtains.  I want something retro looking in red, pale yellow and black.  Looks like I'm going to have change my "retro" idea as I can't find any material that's even close to what I want.

I haven't gone to any stores yet to look at pre-made curtains/valances, but I think that may be the way we'll have to go.

As far as replacing the cushions...I found large rectangular foam pieces at JoAnn Fabrics, but read somewhere about using futon cushions.  Any thoughts or ideas out there on this?
