Text - Type out the letter “V” or another letter you like. Make it a font that's thick enough. Make it very big (size 150-200) and give it a color.
The problem is the back part of the ring needs to be behind the text. Select the Knife tool and cut the ellipse to the left and right of the letter (near the “top” of
the ellipse) – just click and drag the knife over the path, let go and you should see a new point.
In the Layers panel, select the top layer (one you just created, = the part of the ring that we want behind the letter), and drag it under the letter layer.
