I found enough material to make valances for my 4 livingroom windows. Material is the same material as curtains except for the color. My curtains are a cream color the new material is white. I tried washing the curtains and added bleach but they are still cream colored which I do like. So how do I get the new material for the valances to a cream color? Daughter says use tea bag dye, but won't that make it brownish color not cream? Please help. Thanks for any advice.
