SHELL BORDER WITH S SCROLL : Page 107
After completing the shell, the "S" border is put on with a No. 3 tube. Use a contrasting color. By taking a close look you will see that the "S" is started at the front of the shell and passes across and back to the second
shell. Notice carefully where the second "S" is started. This border is completed with the "S" Scroll. If you care to go into more detail; you may do so as shown above.
