Skeletons in all sizes are hung with empty picture and window frames for a kind of high-contrast look. Instead of painting your patio wall black for the occasion (yeah, right), use a large roll of black paper as a backdrop for your bone-white skeletons and frames. Play around with the lighting until you get the ghostly look you're after. Hang the skeletons by monofilament
(fishing wire), which you can find at a hardware store. This should be a quick and easy project.
