This fabric treatment is a lot like scoring paper to get the right folds. However, in this particular design, the use of "scoring" is not to create a fold line but to make a design detail in an otherwise plain fabric.
Be pretty in pink with this summery ensemble. You can add swirling patterns on top of your matte background then highlight the design with a thin white border around it. You can then add silver beads on top to finish the effect.
