Introduction: Hardened-leather Mari Gras Mask

Make your own Mardis Gras mask out of water-hardened leather.

Step 1: Material

Start with vegetable-tanned (also known as saddle-skirt) leather. I picked mine up at a local Tandy Leather. Get 5/7-weight leather (that is, between 5/64" and 7/64" thick). Thicker is OK, though you'll get more shrinkage (less soak-time may help that). Thinner won't harden as quickly, will be brittle and won't hold a shape very well.

You'll also need paint suitable for leather (fabric paint usually works).

Step 2: Cut Pattern

Cut a mask pattern, allowing for about 30% shrinkage.

Step 3: Cool Soak

Soak leather in cool water for 10 minutes.

Step 4: Heat Water

Heat a pot of water to 180°F.

Step 5: Hot Soak

Soak in hot water for around 90 seconds. The leather will shrink, curl and thicken, and then start to uncurl. The longer you soak it the stretchier it will be at the start and the smaller, harder, thicker and more brittle the end result will be.

Step 6: Shape

Once the leather comes out, you have about 5 minutes to stretch and shape it before it becomes stiff. For a good face-shape be sure to add bumps for the bridge of the nose, eyebrows and cheekbones. If you have any dangly bits they can be twisted or braided, and they will harden into whatever shape you set them. Over the next 10 minutes, give it a pinch every now and then to make sure it stays in the shape you want, then let it dry overnight. By morning, it should be hard as wood.

Step 7:

If you decide now that you need to expand the eyeholes or change the outline you can use a drill or saw. Otherwise, you're ready to paint it, using a paint suitable for leather. I used several coats of "3D" fabric paint. Mardi Gras colors are green, purple and gold. Add ribbon-ties if you like. Have fun!

    Never to late to add something I guess ?

    You can harden leather without shrinking it, by using soda(the chemical, not the drink :-) ) which you dissolve in water at 180f or even a bit more, BUT do not put the leather in the water until the temp is below 176f(but not below 167f).

    The longer you let the leather stay in the Water, the harder it will end up. If you keep it in there until no bubbles emerge, it will be as hard as wood when it dries.

    Use around 4 spoons for 1L of water


    You seem very knowelgeable

    my question is . is there some thing that can go onto a leather mask to have it stick to your face and be able to take it off and replace it again by not using spirit gum. Id like to be able to take it off then replae it back on my face without any kind of glues if possible.

    Thanks for any kinda help.


    I work with leather and hadn't thought of that use! (Though historically you are perfectly justified..) recent advancements in leather conditioning (since the 18th C) have made modern costuming in leather more durable and comfortable.

    You should start by getting a friend that you trust to help you create a deep (or full) face/head mold..don't forget to leave breathing holes.. Then use that to create a positive mold of your head in a durable material both moisture and heat resistant. This will keep you from both sticky and hot procedures in forming.

    After you cut your leather (to a pre-designed paper pattern which saves heartache and leather) refine what yo want to acheive. There are two population treatments for this now which give similar results. 1. (More modern) water down water solvable wood glue by 50/50..Elmer's classroom craft glue will not give good results. Soak the leather. Spray a release on your head mold. Remove leather and after five to ten minutes and form it as desired on your mannequin.

    2. Old timey...better(?) way.. Safely melt wax to a clear state liquid. (Flammable, learn to do this safely). Heat oven to 400 deg. F and wait for full temp. Place finished leather piece into oven and heat thoroughly..about five to eight minutes for detailed face mask.. Now remove and quickly plunge into melted wax (use safety precautions and very heavy rubber gloves..especially for the next step..). Let soak two to three minutes fully submerged and pull it out. Time is important! Form it to your mannequin head as desired and let cool. You can make minor adjustments and such later but it must be pretty accurate the first time. Good luck, use extreme care and all safety knowledge.

    400 is way hotter than it needs to be for the oven temp. 165-200 degrees is fine.

    You seem super-knowledgable. Have you posted any Instructables yet? I bet a lot of people could benefit from your accumulated wisdom.... :)

    I'm in the middle of one which is taking some time, an overstuffed leather couch from the shattered frame outward to the paint abraded surface. A huge long project. Inbetween weather I'm building a large hot tub deck which has to swing an enormous 8 tonne hyper dynamic load...which will lend heat to a hydroponics green house...from the hot tub out building...heated partially by sun and partially by drier output.. So I've started filming, picture taking, bumping into my neighbor's car with a renal excavator..oops!...but it will be a few months in finishing each project and editing. My next dream is a full leather and thermoplastic sheet, metal strips, rods cams and gears full body robotic suit as costume head to foot for steam puck 18th C period functioning automaton suit...But that's going to take a year to be fully functional and lit throughout with fiber optics...I'm excited but running in too many directions as you can certainly relate...(?). Thanks for the huge compliment!  I've been a student of everything for most of my 52 years and had a dad that passed on his 'renaissance man' learning..so I have been very blessed.

    Very informative... Can you sculpt with this process or is there a different way to soften the leather in order to manipulate it??? For example to make original roman armor? I sculpt female and male life sized torsos with fiberglass but would like to learn how to do leather torsos? Thanks...

    if you can cover your fiberglass torso with heavy waxed paper sprayed on both sides with plenty of release, you can create a sturdy mold of that torso...an identical match to it. Sand it clean smooth when finished and re-enforce it for strength. Now cut your leather to size, soften it with water, wax, oil or lacquer as desired and lay it perfectly positioned over your positive mold. (Be sure you have prepped your molds with release or you're just making a leather sandwich). Now apply the negative mold while the leather is still hot. Apply as much pressure as you dare. If you built them up well, they can withstand several hundred pounds. Now start the fans to cool your creation. Don't worry about drying it yet as it takes about a week to be sure that the stretch is permanent in all the subtle details. In a week it will be what it will be. You can carve, cut and trim the still damp leather. Resist dyes or conditioners until it is dry. I tend to leave mine on the positive mold to work on it and leave a slow gentle fan on it until it dries. Shrinkage should eventually 'pop' it off the mold without distortion. If you're planning on doing this for an Easter play at this point I would suggest going and buying thermo plastic sheets that you can pop off every half hour and paint...


    You can, and the leather is quite soft for the minute or two after it comes out of the water. You only have a few minutes before it becomes stiff though, so you'll need to work fast (or apply to a mold). I borrowed this technique from people in the SCA who use it to make armor, so it should work just fine.

    if the leather is dyed before will this work? will it hurt the dye? can it be dyed afterwards?
