When it comes to costume accessories that can make a dramatic change to the shape of your face with minimal hassle, there's nothing better than a fake nose. Fake noses are an essential part of many theatrical, Halloween or costume play costumes and can give you a modest change or help to create a dramatic character face. Making your own homemade nose prosthetic pieces is also one of the easier forms of facial latex works—one that doesn't require a full life mask in order to customise and shape to your liking.
Sculpt the nose in oil clay. Hold the finished nose shape up next to your own while looking in a mirror to judge the size and proportions and make sure you like the way it looks. Make the back of the nose flat where it's supposed to attach to the face.
Adjust the colour of the liquid latex. Most liquid latex has an orangey-beige colour once dry, so it's a good idea to adjust it to be closer to your actual skin colour by mixing it with some acrylic paint; bear in mind that the dry colour will be darker than the colour when it's wet. Don't worry about getting the colour perfect, and err on the side of too pale; you can finish matching the colour using make-up later.
Coat the nose sculpture in liquid latex. Use a disposable brush or rag to cover the nose sculpture (except for the back) as if you were painting it. Apply at least four coats of latex, letting each one dry before you add the next (this will take 10-20 minutes for each layer; you'll know when the latex is dry because it will firm up and darken in colour).
Peel away the latex nose from the clay. If you have to manipulate the shape of the clay to keep from stretching the nose shape too much, do so (though it should be easy to peel away the latex without too much stressing of its shape). Try to remove all traces of clay from the inside of the nose.
Line the inside of the nose. Give the inside four or more new layers of latex, applying them just as you did with the outside to make the wall of the nose stiff enough to have body on its own. If the nose is particularly large or long, stuff part of it with small pieces of latex-soaked toilet paper. Leave room for your nose, erring on the side of too much empty space. Let dry.
Create nostril holes using scissors or a craft knife; these are necessary for comfortable wear and breathing.
Apply the nose. Use spirit gum to adhere the nose over your own, applying the gum only to the edges of the back of the nose. Apply thick stage make-up to the nose itself, and to the surrounding skin on your face, blending the make-up at the edges.
