This is a mini-sized shooting table so simple in its design, its ingenious.
It consists of a 39 x 20" sheet of opaque Plexiglas, and two bead-stop window draw pull-strings. Pull the strings through the holes in the Plexiglas until the desired sweep, or scoop is obtained.
Set it down on any tabletop, and you have a seamless background for a small setup of jewelry, models, or collectibles.
