For my sewing room curtains, I was able to save some money by using the leftover length of fabric from my bedroom curtains, and I was able to still do a style and color that I wanted. This valence is extremely simple-- no pattern required! I simply hemmed all 4 sides of my panel of fabric, and folded the top half over to create the casing for the curtain rod. The buttons tack the casing down and that was it! I used 10 shiny mother-of-pearl type buttons. Total cost was $5 for the buttons (and those were even 1/2 off!).
Decorating pictures next time!
