Place your item on a piece of foam. If your object doesn't have a flat bottom, use toothpicks, Popsicle sticks, whatever to raise it up so that you can easy move the piece your spraying without actually touching it. This way you can move the piece easily by picking up the foam and not the actual object to turn it around so that you get all sides equally covered with spray paint. Pebble style foam that comes packed in boxes around TV's and knock down furniture works the best as the spray paint doesn't melt it. STYROFOAM will melt if the spray paint is applied very close to the surface.  Using light coats of paint will lessen any melting of the foam.  I use my blocks a few times and then throw them out once they start melting away.
