A: I get asked that question many times so here we go. I mainly use a Dip Pen and Black Acrylic ink when drawing stuff like the two images that accompany this post. They are coloured up using Watercolours (see pic).
A couple of pics using the materials seen in the pic above.
I use chisel tip marker pens when drawing 'live' and doing big demo pictures. I can and do, use anything from calligraphy markers, fountain pens, fineliners and brushes for sketching and Doodling....Variety is good.

Thanks for the question
