Since I wouldn't be able to stay the entire day, I chose to work on small pieces in pen and ink.

I brought along three pieces that I had started a long time ago (see post on 26 September 2014).
Beginning with the first one of three sketches featuring Queen Conch shells, I finished the first Sand Dollar and started on the Conch shell before I had to leave to for a number of appointments.
I will post this drawing at a later date once it has been completed.
