Whatever form the flower designs will be used as car sticker, it would produce a highly artistic works of art. This is not out of the mix of colors that should be absolutely precise. However, the method of black and white or monochrome can also be applied if you do not want to have a lot of color.
The most important thing to note is do not pick the material sticker black if the car is also black, and do not choose the white sticker material if the car is also white. Hadeh, mostly kidding ..!
