I would say to check with the experts. You could check at the manufacturer of fabrics sites. They usually have free patterns for their lines of fabric to show how they are being used. Going modern is a simple way to make it timeless in design. I like the traditional look myself. A quick look at one of the magazines on the stands will help you to see what is in style as far as colors go.
It would be interesting to see what you come to believe as hot trends go.
