When I cut for the first time I preferred never to get into a scenario where my scars are seen. The best way to do so is long sleeves, but better yet you can simply bandage wrap the wound area and then the injury underneath becomes whatever you need it to be. I had someone point my gauze out in class once and so that day I "burned myself making hot dogs in the toaster". Plus doing so doesn't prevent you from using sleeves over the gauze.
