You'll notice at the top of this photo, you can sand more, or less depending on how much shine you want to show through. There is another example below.
The more you sand the flatter the surface of the frame becomes, and more glitter shows through, see the top right portion of this frame.
Then I started on these two frames. For these I added a super fine glitter to the paint.
It was the same with the blue frames as well.
I eventually added enough glitter to make them shine however.
This is the only frame I didn't repaint. It already had Japanese images stamped on it, and I wanted to work with those still on there, so I didn't repaint this frame.
