I found dinosaur skeletons at Dollar Tree that actually would be fun for numerous projects. I saved a T-Rex skeleton for craft room decor, and I chopped up a pterodactyl for this spider. I gave the "bones" a bit more depth by sponging on an ivory color, then dabbing a dark bronze onto some areas for a more fossilized look.
Materials: plastic toy dinosaur piece, ivory crackle bead, ivory bugle beads, multi-tone metallic seed beads, gold wire
