I am over half-way through the Irene Wellington Copy Book. This week I am experimenting with holding the pen like I did when I was little (I used to hold it with my thumb, index finger, and middle finger wrapped around the pen with it resting on my ring finger). This seems to give me a little more control by allowing me to go with the natural curves my hand wants to form. However, holding the pen like I have been for the past year and a half (I was trying out holding it with my thumb and index finger clasping the pen with it resting on my middle finger) seems to allow for more freedom of movement.
I am a very technical writer, so I may go back to holding the pen like I did when I was a little girl sometimes. I really prefer more control.
