It will take awhile for the bleach to show up so be patient. You might have to wait or guess where you put the next line depending on you style ( depending on how thick you put on the bleach 30 sec- 2 minutes) Make sure you are working in a well ventilated area and have cloths on that you don't mind getting some bleach spots on.
Good luck! P.S. for variation you can make a stencil out of duck tape and then use the spray method to fill in around it.
You might also want to wash this by itself for the first few times.
