Start by measuring over the
nose, from the cheek bone to the other side cheek bone.
The cheek bone is up from the
corner of the mouth about 2"-3".
This measurement would be
where you want the rings to lay.
Then measure from the cheek
bone on one side, over the poll to the cheek bone on the other side. This
will give the poll measurement. An example of a size would be: 6" x 20".
