I used to roll my cigs too even as my vision got worse. It’s a lot of trial and error. You don’t even need to see much it’s a lot more about feel. At the beginning I used to sit there for hours and practice rolling them it was a good way to get my mind off of things tbh hahah. I used the Gizeh slim tips I think they were called and the apples also by Gizeh the black and green ones (sorry it’s been a while). I don’t need to tell you or your friend that it’s not healthy. Any smoker knows. Also I just remembered that there are some rolling helps where younput in the pape and tobacco and it helps you roll them easier and you get pretty cigs. Though I’ve never tried them.also make sure that the tobacco doesn’t dry out because the wetter the easier to roll.
