When it comes to sketches I prefer a good ol #2, Prisma colours and Micron to ink. When it comes to painting I ONLY use acrylics, I cant paint with water colours to save my life.
Well.. I love traditional watercolors for when I'm doing skies and such, but for more intricate things/experiments. I tend to do watercolor pencils/ regular colored pencils because I usually only have my dry medium sketchbook with me. For average doodles, graphite is my friend. I am pretty good at charcoal too, I just hate the mess. Acrylic is what I use to paint custom designs on my t shirts. (Along with bleach pens)you could say I'm a person with many talents. (I'm also a great trumpet player!)
