Have you seen those beautiful giant keys? Please tell me you have. They’ve been popping up on Pinterest and just last week, my favorite blogging couple over at the Navage Patch, shared how they made some for themselves. So clever, but with my limited wood working skills there was just no ways I could make something so gorgeous. And I really, really wanted one. A lot!! So I had to make another plan. If I couldn’t make a wooden one then maybe I could make this giant rustic faux metal key instead.

Our giant faux metal rustic key

How to Make a Giant Skeleton Key

Our faux metal key is about 50 cm long, or 20″ for my American friends and it was one of those projects that really frustrated me at times, but I am so happy with how it turned out. If you’d like to make one all you need is some cardboard, paint, coarse sea salt, nutmeg and expanding foam. That stuff you use to fill gaps with. Any brand will do.

All you need

I found this basic key on the Graphic Fairy and used it to create a template for our key.

Cut a key template

I considered going for something a little more intricate, but I think this technique is more suited to something simpler. Once the key template has been cut out of the cardboard, grab some of that expanding foam and spray it all over the cardboard key, and wait for it to dry completely.

Spray on the foam

Ours took about a day. When it’s dry, use a craft knife to carve out the key shape. Start off by just cutting away large chunks of the foam and then whittle away the rest, little bits at a time. I promise it’s easier than it sounds and I found it very therapeutic. And if there’s any expanding foam left you can lways make this adorable fairy toadstool

Carving the foam

Don’t worry to much if there are gaps or air bubbles in the foam, it will add to the faux metal effect later.

Gesso to smooth out the ridges

Adding the Rust Factor

We used some Gesso to smooth out any rough edges, but if your carving skills are better than mine, it’s probably not necessary. Gesso is the stuff artists normally use to seal their canvas before painting and you’ll find it at most craft stores or you can make your own. Paint the key in a copper brown color. You can use acrylic paints or spray paint, whatever you have in your craft cupboard. Once the paint is dry, spritz the key with water and then randomly sprinkle some coarse sea salt all over the key. The sea salt melts and creates a barrier for the next layer of paint. Wait a few minutes for most of the water to evaporate and then spray the key a deeper darker brown.

Add some salt

When the paint is dry, just brush the salt off and you’re left with this gorgeous pitted effect.

Beautiful pitted effect

Now for the nutmeg. Bet you were wondering what on earth that had to do with the whole equation 😉

Add little dabs of glue or mod podge and sprinkle the nutmeg all over the key to create some yummy delicious rusty awesomeness.

Spice it up

Be generous with the nutmeg, especially in the air bubbles. That’s where rust would naturally form if the giant faux metal key had been lying in the rain and snow.
