The loop at the corner where the top edge (A) and the curved edge (C) meet is meant to help attach the wing to your wrist. I found it easiest to use old hair ties through these loops which slipped around my wrists easily when I was putting on the wings.
The loop at the corner where the top edge (A) and the side edge (B) meet is meant to help attach the wings to your neck. Pass a ribbon through these loops on each wing, as shown in the drawing, and tie the ribbon around your neck. If this is uncomfortable, use the loops to pin the wings to your clothing instead.
