clorox bleach pens

[righteous-rage.livejournal.com]

I'm making a t-shirt for my boy for his birthday and Ive been spending my time cutting out the quote, and I am going to be using a clorox bleach pen and I was trying to find in the memories someone's post of a shirt they made with the bleach pen. I was just trying to make sure I was going to go about it the right way, and how long to leave it on, how to go about washing it off, any help would be fantastic!! <3
