I love these bad boys. For all of my illustrations, I will first sketch out the drawing in pencil (I prefer mechanical pencils due to the thin tip and laziness of not having to sharpen it). Once I have my final sketch, I will then ink my lines using Prismacolor Premier fine line markers. They come in packs that range from .005 to .08 tip thickness. I find myself most often drawing with the .03 thickness, but it is nice to have a small range in case you need a very tiny detail or something a little bit more prominent.
