Use aluminum cans to make jewelry, coasters, ornaments, wreaths and candleholders. To make a simple candleholder, use a pair of craft scissors to cut off the bottom of the can. Use sandpaper to round out the sharp edges. To securely mount a pillar candle, pound a nail up through the middle of the bottom of the holder, and slide the candle onto it.
Make jewelry such as a pair of leaf earrings out of aluminum cans. After cutting off the top of an aluminum can, cut out a leaf template, and trace two onto the can. Use a pair of scissors to cut out the shapes, and sand the edges down. Use a pair of needle-nose pliers to bend the veins into the leaf. Finally, punch a hole in one side of the leaf, and insert an O-ring attached to earring blanks. To make a leaf cluster, attach the leaves to one another with O-rings before adding the earring back.
To make ornaments out of aluminum, trace a shape such as a butterfly on the aluminum can, and cut it out. Punch a hole in the shape for the ornament hanger or string. To paint the ornament, sandpaper the surface, and then add a metal primer before the paint.
