Levi Strauss invented the process of making pants out of denim. Now they are called blue jeans. 
I really like blue jeans but sometimes I like jeans that are black washed. Like they are faded in some areas.
Faded and torn jeans are in style right now. You can fade your own jeans using lemon juice.
I never heard of the lemon juice idea! I think I will try that with a new pair of black jeans I have. I wonder how they get the whisker affect?
Scraping and rubbing with pumice stone while the jeans are folded can give that effect. 
I have a few projects now I will have to try on my jeans. I may use these ideas on an old jean jacket too.
Customizing an old jean jacket is a great way to express your creativity.
I have some rit dye. Maybe I could dye it first to give it less dingy and dirty then use the pumice to give it character.
Use 1 cup of salt into 2 cups of hot water if the jacket is 100% cotton to encourage consistent coloration.
Ok. The jacket is also Levi's brand I have had it for many years and it never goes out of style. I am just going to freshen it up a bit.
