I stole this idea from my wife. she used it to display her ear rings.



What is used is one half of the screen that is used in a window without permanent screens. The screen halves slide back and forth to fit difference size windows.

there is enough slack in the screen to allow you to put the pin into one of the screen holes and back out through another hole lower down the screen.

This would look very nice if you are a wood worker and made a wooden frame. If you make one leave a little slack in the screen. In this case the screen is plastic.
