inDevelopment – Tutorial: TOS-Style Andorian Antennae

Welcome to our first tutorial! Today we are going to show you how to make yourself some antennae for your Andorian costume. This tutorial could also be adapted to make horns if you are so inclined. This will make you a nice pair of TOS-style antennae; they are a bit fragile, but if you take care of them they will last for years to come!

To wear these, you will need a wig. Check out Epic Cosplay or Arda Wigs to find one that suits your character!

You Will Need:


• Crayola Model Magic air-dry clay in white


• Paintbrushes: one large, and one for detail.
• Acrylic paint that matches the makeup you plan on using. Take your makeup to a craft store like Michael’s or A.C. Moore and match it to acrylic paint for crafts. This type of paint is very inexpensive and is meant for painting woodcrafts and stencils.


White glue, like Elmer’s.


Paper plates
Push pins or thumbtacks
Newspaper or other scrap paper

Optional, But Nice:


• Paper or plastic paint pallette
Clay tools to help sculpt your antennae
• Not pictured: Sharp scissors, X-Acto knife

You Don’t Need:


• A cat all up in your business


• Well, OK.

Let’s get to work!


Work on a glass plate or your paper pallette so the clay (Model Magic isn’t actually clay, but I’m going to call it that) won’t stick. Divide your clay into quarters. You can cut it with scissors and they won’t get gunked up with it. Store half in a plastic bag for later—but use it soon, or give it to a friend who will, because it will dry out and become unusable. Roll your two remaining quarters into balls. This is what you have to work with for your antennae.


Start by rolling the clay into a cylinder with your hands. You may realize at this point that Model Magic is very soft before it dries, so you definitely don’t want it to be too narrow. Hold the cylinder on top of your plate and start flaring it out at the base. This is how your antennae will stay in your wig. We’re just getting the basic shape here; you can work out the details as you go. Keep some width at the top too.


Press your finger into the end of the cylinder to begin making the “cup” shape at the end of the antennae.

Gently mold the clay with your fingers if you want the antennae to look “knobby”, like the few we saw in TOS. Work out the detail on the ends of the antennae. Do you want an indentation at the end? Use your clay tools or the end of a chopstick. Your imagination and, er, sculpting skills are the limit here.

Model Magic can be very frustrating to work with. If you end up rolling your antennae into a ball again out of anger, so be it! Or keep going, and remember—you still have half a package of clay left.

If you want to make the more insect-like, segmented antennae we see on Shar here, roll your antennae a little thinner and use a flattened-out piece of clay to wrap around the base. Work it into one piece with your wooden clay tools, if you have them.


For a more uniform look, or if your proto-antennae are just too bulky, cut any extra material off the base with a sharp knife.

Small imperfections like fingerprints won’t be visible after you paint your antennae. Keep in mind that once the clay is completely dry, you will be able to gently sand it. If you have large indentations or cracks you’ll want to smooth them over before leaving your antennae out to dry.


Gently lay your antennae out on a plate with a piece of wax paper, parchment paper, or paper palette on top of it. Tear off tiny bits of newspaper to support the antennae. This is really important! Most of our antennae have a bit of a “twist” to them from the position they dried in. You can either go with this, and figure out which one’s left and which one’s right after the fact, or try and support the antennae as well as possible using the newspaper bits. Be careful not to let any sharp creases in the newspaper make indentations in your antennae.

Keep your antennae somewhere out of the way to dry! This might be an issue if you have cats, kids, or nosy friends around. They will need at least two nights to dry; this really isn’t a night-before-con project. They will be dry when they are no longer tacky or squishy to touch. You might see a few cracks in your antennae after they’ve dried, especially if they are on the thick side.

Grab your paper plate and stand your antennae straight up. Stick a push pin through the bottom of the plate to anchor each antennae. Sand your antennae lightly, if desired, and apply a layer of white glue. This will help reinforce them, prime them for paint application, and fill in any minor cracks or imperfections. You may apply another layer once it dries for more coverage.


Once the glue is dried, it’s time to paint! Squeeze some of your base color out (the one that matches your makeup) on another paper plate or your pallette. Paint away! You may want to leave the base white so it blends in with your wig. Once the base layer is dry, you can use a darker shade, or mix your own, to add detail.


When you’re satisfied with your paint job and it’s dry, it’s time to try them out in your wig! Cosplay-grade wigs have nets that can have large holes. Simply take your antennae and pop them through each side. Experiment with different positions until it looks right. TOS-style antennae sit a bit further back on the head, but, as we have seen, Andorians are a diverse bunch.

It’s helpful to use a styrofoam wig head to style your wig. You can pick one up at a costume or beauty supply store. You will need to adjust the hair around the antennae. If you are using a longer style, you can use white bobby pins (also available at a beauty supply store) to help secure the hair around the antennae and hide the wig net.

If you’ve never worn a wig before, here is a video on how to do just that.


It’s time to wear your antennae! As we’ve said, they will last a while but can still be fragile. Be careful not to bump your head or let someone snap one in half with their flailing arm at a dance party in Ten Forward. If you are going to a convention, pack some super glue and extra paint just in case.

Be careful when storing your antennae. Wrap them individually in some paper towels—even when dry, they may stick to plastic or each other and remove some of the paint. Store them in a hard container so they don’t get crushed.
