Fine liner is my favourite medium to draw in purely because you can be as messy as you like and it doesn’t matter!
For all my drawings I sketch out the rough shape in pencil and then go over it in a fine liner. I tend to avoid large drawings as I prefer drawing with more detail on a smaller scale. The smaller the fine liner, the more detailed the sketch, and also the longer it takes (as I found out during my exam). What do you think of fine liner?
