How to make Casts - Instructions and Videos


Tiny baby hand and feet are so tiny and fascinating, and a baby casting kit is the perfect way for you to create exact 3D replicas of them, making baby keepsakes that you can treasure forever!

Commonly known as Life Casting, baby hand and foot casting is a completely safe and unique way to capture your baby’s tiny hands and feet. Every little line and wrinkle is replicated exactly, the fine detail of little fingernails and fingerprints is truly amazing and we are certain that you will not be disappointed with the end result!

What's involved in the Baby Casting process?

Detailed instructions come with all of our baby casting kits and the process itself is really easy to do yourself at home. You will need a helper to assist you, and we recommend that if your baby is too wriggly to make their hand and foot moulds at the first attempt, to then wait and do it when they are fast asleep. Baby Casting will not hurt your baby at all and all of our materials conform to EU safety standards. 

First of all, an impression is taken of your baby’s hand and/or foot which then becomes the mould to pour the plaster in to. To make the mould impression, Chromatic Alginate is used, a baby safe seaweed-based compound used commonly by dentists for taking dental impressions. When mixed with water, the alginate soon starts its colour change process and its rapid set time is perfect to take your baby’s hand and foot mould with ease. Your baby's limb is only kept in the mixture for a few seconds whilst is sets, unlike a lot of other casting kits that can take up to 10 minutes to set! Once the mixture has set, baby’s limb is eased out of the alginate. When the alginate has set, it's similar to a thick blancmange texture and the alginate impression mould is not ruined when baby's limb is removed from it, it retains its shape perfectly!


Here is a basic pictorial of the process so you can get an understanding of what's involved:

All of our baby casting kits come with enough BabyRice alginate and high quality casting plaster so that you can take a few alginate moulds of your baby’s hands and feet (as it may be a bit tricky to get it right first time) - each 500g bag will make around 6 casts of a newborn baby and 2-3 casts for a 2-3 year old toddler, this gives you lots of opportunites to make sure you get the best cast possible!  We also sell our alginate, plaster and paints individually, so if you ever need any more materials you can buy extra at the time of your order or at a later date. Once the baby hand and foot moulds have been made, the next stage is to fill the moulds with casting plaster.  All of our kits come with high quality stone casting plaster (not plaster of Paris which is too soft and not durable enough to last more than a lifetime).  The casting plaster is simply mixed well with water and then the mixture is poured into the impression mould.  After around 4-12 hours the alginate can be removed from the plaster cast - and this is another fun part! The alginate is gently broken away with your fingers in small pieces and chunks from the plaster cast and once all the alginate has been removed, you will have your baby hand cast or baby foot cast and will be wowed by it!  The casting plaster takes a few days to dry out completely (depending upon the temperature of the room you are keeping them in), and once completely dry you can then paint your casts in your chosen colour.

If you choose to purchase one of our affordable basic material baby casting kits and then decide at a later date that you'd like to frame your casts, we make beautiful 3D box display frames here in our workshop that are specifically designed to showcase baby hand and foot casts. Our small 6x5" frames are suitable from Newborn to around 6 months.  And our medium and large box display frames will display a 6x4" photo of your baby and the display area is large enough for a foot cast of a toddler size 7, so there's plenty of room for larger baby castings!

You can see some examples of our customer's finished baby hand and foot castings, we think you'll agree that they have done a fantastic job.  Proof that you can make a mini-masterpiece with a helpful assistant and a bit of patience!
