These are the instructions I found before...I am hoping though I wont have to dye it that I can leave it white...I guess I'll see when it arrives....by the way I bought this particular valance because it was 1.29 on ebay brand new!! Can't beat that!
Prepare the Coffee Dye
Brew a pot of coffee as you normally would.
Choose a container that when filled with water will allow your item to float and doesn’t require cramming the item into it in order to wet the entire item. The goal
is even saturation and even color distribution. Fill the container with water.
Mix the coffee into the water.
Conduct a swatch test. With coffee, this is important before dying your intended item so you can get a feel for how quickly the solution you’ve mixed will darken your fabric. Either cut a small piece of excess fabric from your item, or use a small amount of similar fabric.
Wet the fabric swatch with clear water and then submerge it in the coffee dye solution. Keep the fabric moving so that no creases or folds form that will allow excess color to accumulate. Keep checking the swatch for color depth.
Remove the item when you’re satisfied with the color and rinse it in clear water until the water runs clean.
Examine the swatch for color depth and consistency. Remember that the color will be lighter when the fabric is completely dry. Keeping this in mind, use the test swatch to determine if the fabric you want to dye will give you the result you want, and to decide approximately how long you will need to let it soak in order to achieve the right shade.
Dye Your Item
Soak your item in clear water so that it is wet through.
Shake the item out so that there are no folds or creases that might cause the coffee to absorb unevenly. Then submerge the item in the coffee dye.
Pull the item every few minutes to check for color depth, and in between checks keep the item moving to encourage even color saturation.
Remove the item from the dye and rinse in clear water until the water runs clean.
Wring out the excess water.
