This thread could also be called "Tarpaper a'la Robert". He got on me during my O'Neills build about my tarpaper. Said I should use tissue instead of the material I was using. He says that he paints his by the sheet and hangs to dry. Surely he build a scale clothesline with clothespins for this task. I found that pre-cutting the strips worked better for me. What follows are the steps I use to make the strips.
Start with a tissue. They will all have some part at the end that you can't use so cut that off. Here is the first tip. I take a sheet of plain paper and fold it in half. Put the tissue inside the paper and cut with a straight edge and new blade.
