Painting flowers of old jeans will never be a win. It's such a relaxing past time, and when you're done, you have a cute new article.
Painted jeans start with old, faded jeans. The kind where the texture you feel when wearing them has changed from when you first washed them just from putting them through the wash so many times.
Choose two colors, and draw simple images. You'll have created a simple pair of paints with fabric paint. These kind of jeans are worn with a relaxed outfit, like a basic graphic t-shirt with converses.
