I am doing the lines project. Just so you know, put the red, black, blue and yellow on my left, and purple and green on my right wrist. Go see IzzyBlueburryPie's page about what the colors mean! And please do it! Wattpad won't let me put the pictures up so I will try again later.
I haven't fully self harmed yet but I scrape myself, so I put red on the left.
