Step 1: Acquire Ingredients

Acquire the required ingredients. I found most of these to be quite affordable at home despot.

1. Cement : I used "SAKRETE" which is a cement that comes premixed with reinforcing fibres. Cement on its own is quite weak without some sort of reinforcing...hence all the gravel and rebar when you want to build something structural (like a highway overpass). The 50 pound bag will make enough "wallets" to last me a lifetime.

2. Reinforcing mesh : I used some mesh which is probably intended for stucco work. Again the same idea, you need some underlying armature to hold the cement together.

3. Metal shears or wire cutters to shape the mesh

4. A non-dairy whipped topping container to mix the cement in. You might be able to get away with an old dairy whipped topping container but it's risky

5. Liquid Cement Color : A fun way to create wallets in a variety of colors ranging from gray to gray-orange to pretty-damn-orange.

6. Household gloves; cement can be hard on your hands

Step 2: Assemble Ingredients

Cut wire mesh to form the "skeleton" or "armature" of your wallet. Do be careful, that stuff is sharp.

Ideally it is best to have a mold to contain the cement around the skeleton while it sets up. One possibility is to use your current wallet. Just pour cement around it to make a negative. Once that negative sets up, break it apart and grease it up for use as a form to make a positive. Keep in mind that this will almost certainly destroy your wallet, but remember that you will soon be replacing the old one with a far more durable cement wallet of similar dimensions.

We ended up shortcutting all this hassle by just using one of the rubber gloves as a form instead.

Mix concrete and concrete color with water in mixing tub. You want the cement to be wet thru and thru but not completely soupy. Pack the cement into your form around the armature. Work any air bubbles up to the surface by taping on the form.

Let cement set up overnight.

Step 3: Enjoy Your New Wallet

Once the cement has set up, you can remove it from the form. If you are using a one-time rubber form (such as a glove) it may be easiest to just cut it away from the cement.

Meet your new wallet. Since cement is such a durable material, it is best to remain on good terms as it will be holding your money for a long time to come. Once you get the hang of it, you can crank these out by the dozens. Varying the amount of concrete coloring gives a variety of final appearances. Clever manipulation of forms can yield a wide range of useful possibilities including drink holder, cigarette holder, toilet paper holder, toothbrush holder, etc.

In essence, anything you currently waste your time holding can now be easily and cheaply held by our new durable friend, concrete.

    I'm not one to leave bills laying anywhere, even at home. But if I make this I would have a pair of hands that can be placed together in a nestled (praying, handshake, etc.) gesture so as to create a space to bookend or conceal the money.

    That's not a cement wallet it's a hand made from a mould.

    If you get a glass hand that they use for modeling stuff in shops, then pour the concrete in there, it should come out all glossy. See https://www.instructables.com/id/Concrete-Lightbulb-Wall-Hook/ for proof of concept. That might work better for not scratching her rings.

    Awesome, any recommendations on some sort of bucket? do ya think i could et by with one of those orange homer buckets?

    True... the project is fine, but the title is misleading. Perhaps "helping hand" or "hand shelf." I typically understand a wallet to be a way to organize money and credentials for easy transportation.

    Fun idea for holders though. Also might consider using a cheap gel mold solution that sets up in minutes. Wiggle your hand out of the mold and pour to get a realistic hand with details.

    I'm thinking about how to make a hand mold that gives a standard hand, like this one, but allows me to reposition the fingers, wrist, to get different gestures (no bad ones!).

    you could do this then cut off the fingers and then screw in joints so it would pretty much be like knuckles and this diagram only shows one "knuckle" but if u want to like make it more realistic u could put a lower and upper knuckle plz mssge me back on what u think of my idea and if u make it dont hesitate to take a pic because i would love to see what u come up with
