There were white and blue linen curtains fastened with cords of fine linen and purple on silver rods and marble pillars; and the couches were of gold and silver on a mosaic pavement of alabaster, turquoise, and white and black marble.
I also used round cord elastic which comes in lots of colours rather than 1/2 ″ wide elastic and it worked just fine, as black and white didn't really match my fabric.
