I doodle alot and i use a biro, make a dot, then continue scribbling without looking until i feel i wih to finish, then i look and stop back at the point i started from. I then use a permenant thick pen and outline what i can see within the doodle, then i sometimes colour it, or fill it in with criss-crosses, lines, flowers etc do any of you doodle? :-) im getting many new characters appearing :-)
