Square Format with background of your choice, many options available online. For the ornament –

1. choose your subject – my dog Duncan in this example – and make a circular selection with feathered edge. You may need to add white around by increasing canvas if necessary as the next step might distort too much.

2. Filter > Sperize > about 75% good starting point.

3. Drag this onto your background file.

4. Still selected add Drop Shadow.

5. The ornament cap is a piece of clipart… you can search it online… Drop Shadow on that too and resize as needed.

6. The ornament cord is made by drawing a straight line then Edit > Fill with chrome effect in Photoshop.
