Bill in Vista,
Sometimes just a simple plastic picture frame (available at
hobby stores and elsewhere) can work well for display purposes.
They can be cut to size in your wood workshop (or your friend’s!)
and have about the right slant. Cover with material of your
choice (velour works well) or spray with flocking. Can be
drilled with holes for displaying earrings, notches cut for
A layer of foam rubber between the frame and its cover will make
it easy to pin things to it.
