These Giant DIY Spiders Are Our New Favorite Halloween Decor

To make the smallest of the giant Halloween spiders, you'll need two foam balls—one should be half as wide in diameter as the other. We used a 2-inch foam half ball for the head and a 4-inch foam half ball for the body. You can purchase foam half balls at a crafts store, or use a crafts knife to cut the whole ball in half. 

Make a head and body for your spiders by hot-gluing a 2-inch foam half ball to a 4-inch foam half ball so the sides touch, as shown. Cut a piece of faux fur that's large enough to cover the foam shape. Pull faux fur around the curved sides of the glued shapes and hot-glue on the underside. Working with one leg at a time, use an awl to poke a hole through the fur and into the foam. Place a dab of hot glue on one end of a 12-inch length wire piece and push it about 1 inch into the hole. Repeat for all eight legs.

Bend a loop at the end of each leg. Cut foam tubing into 9-inch pieces and slip each piece over a leg, pushing it close to the body. Bend the looped end of the wire back over the tube to secure, then hot-glue tube to the fur. Bend the wire to shape the legs as desired. We suggest using adhesive strips or hooks to secure the spiders to your stairs, mantle, or display the Halloween house decorations outside of your home.

This Halloween spider is perfect for decorating large spaces like a holiday mantel, fireplace, or a set of double doors. You'll need a foam ball and a half-sphere wire globe for these spiders; we used a 4-inch foam half ball and 8-inch half-sphere wire globe like this Green Wire Topiary Form, ($9, Amazon).

Make the head and body form by hot-gluing the foam half ball to be touching the wire half globe. Cut faux fur pieces to cover the shape and pull the faux fur around the curved sides of the glued shapes. Use hot glue to secure the fabric on the underside of the shape. Working with one leg at a time, use an awl to poke a hole through the fur on both sides of the body. Thread a piece of wire through, distributing the length equally on each side. Repeat four times to make eight pairs of legs. Hot glue the wires on the underside to secure.

Bend the wire into a loop at the end of each leg. Cut foam tube into 18-inch pieces and slip each piece over a leg, pushing it close to the body, then bend the looped end of the wire back over the tube to secure. Hot-glue the tube to the fur and bend the wire to shape the legs as desired. 

We're totally obsessed with this outdoor Halloween decorating look. To make spiders large enough to cover an entire house, ditch the foam balls and grab two half-sphere wire globes. They're large enough to make the spiders and weigh next to nothing—which makes these huge spiders super easy to hang. We used an 8-inch half-sphere wire globe and a 16-inch half-sphere wire globe like this Topiary Art Works Wire Globe Sphere, ($21, Amazon). Instead of hot glue, use zip ties to join the wire globes together to make the head and body form.

For this spider, you'll use two separate pieces of faux fur to cover the body. Cut a piece large enough to cover the head and pull the faux fur around the curved sides of the head globe and hot-glue the material on the underside. Starting where the head and body join, weave a piece of wire through the body globe, distributing the length equally on each side. Loop around the frame on each side to secure. Repeat four times to make eight pairs of legs. When the wire legs are attached, cut a piece of faux fur large enough to cover the body and pull the material around the curved sides of the body globe and hot-glue on the underside—make sure the exposed leg wires are still easily reachable.

Bend a loop at the end of each fo the wire pieces, then cut foam tubing into 36-inch pieces and slip each piece over a leg, pushing it close to the body. Bend the looped end of the wire back over the tube to secure. Hot-glue tube to the fur then bend the wire to shape the legs as desired. Use twine, wire, adhesive strips, or hooks to suspend these giant Halloween spiders from the sides and roof of your home.
