Pastel designs have many different qualities. Some are more flat or soft, such as chalk pastels, or more pop art in feel, where the colour seems very dense and vibrant. If you want the biggest effect from your choices, use pastel shades and texture together.
A flat pastel can work wonders in a modern wall for a bold effect, whilst using light pastels with a delicate texture or pattern can make them feel even softer. This pastel peach and white Roman Blind folds gently and gives a variation to the quality of light that flows through it, creating a more unstructured, country feel.
