It's funny how things change. When I first started this blog over 3 years ago, I was cartooning with a dip pen - to be precise, a leonardt dp250 nib in a Manuscript holder. I loved the lines I got, but hated the mess, and the inconvenience. Since then, I've tried technical pens, fine liners, brush markers - you name it, I've probably tried it, and during that time, I've never been really happy with my work.
Recently, I've been using Letraset Promarkers for some of my colouring, and they can be fussy about what inks can be used with them. As an experiment, I tried japanese sumi-e ink and my dip pen... and I was astounded at the result! Since then, I've been using dip pens more and more in my work, to the point where I've started to order new equipment. My favourite combination at present is a Leonardt DPGEN nib (sort of like a Deleter Manga "G" nib), speedball holder and tesco premium printer paper (it's very smooth), with FW acrylic or Sumi-e ink.
