Hi Claire,
You can see the Zia formation at https://contrafusion.co.uk/Formations.html#other if you scroll down a bit. It is a square with contra lines radiating from the sides. There are some example dances there as well.
I set Sicilian Circles up by getting the dancers to make a Circle, then tell one couple to face another couple and work around the circle telling each couple which way to face. Experienced dancers will see what is happening and quickly start sorting themselves out.
Happy dancing,
John
