Quarterlies should always be workshopped if they're used. They are either experimental calls or calls from higher-level programs, and a quarterly is in the program for at least four months and remains there as long as Callerlab voting keeps it there. The current quarterlies are all from higher-level lists. You've done this call many times, without realizing it. Note that there are always four ends and four centers for this call.
Waves are the most common starting position, but there are many others.
Let's have a look. From lines the ends can be facing in, but from columns they must be facing out. We'll look at two other formations. No request has been refused yet. Of course, you may print a copy for personal use without specific permission.
