Stevie's Art Supplies

[DauphineMarie]

I have always been curious about what tools/supplies Stevie uses when she draws.. I'm watching the interview from 1984 where she shows the painting of Sister Honey, and I realized I have no idea how or what she uses when she draws.. it sort of looks like dark led pencils on poster board, but I can't really tell. I know it's a sort of random topic and I'm sure nobody really knows exactly what she uses, but I thought it might be sort of interesting to see if anyone had any guesses.
