People sometimes ask how long a cast takes. The answer depends on whether you mean the moulding, about two minutes, or the whole thing, closer to two weeks.
The moulding is the bit parents see. Everything after that happens in my workshop. This is what that process looks like.
Step 1: The mould (2 minutes)
I use a material called alginate. It's derived from seaweed, completely skin-safe, the same stuff dentists use to take impressions of teeth. It starts as a powder, mixes with water into a smooth paste, and sets at room temperature.
Your baby's hand or foot goes into the mixture. I count down. The alginate changes from liquid to a firm, rubbery gel in about two minutes. The baby barely notices. I always do this when they're fed, warm, and sleepy.
Once set, I gently wiggle the hand or foot free. The mould captures extraordinary detail. Every crease. Every wrinkle. Every tiny fingernail. The alginate is so precise it can pick up fingerprints.
Step 2: The cast (24 hours)
Back in my workshop, I mix a fine-grade casting plaster and pour it carefully into the mould. This is the part that requires patience. Too fast and you trap air bubbles. Too thick and it won't flow into the fingertips. There's a specific consistency you learn after doing this a few dozen times.
The plaster cures for 24 hours. Then I peel away the alginate mould. It can only be used once, which is why the initial mould is so important. What's underneath is the raw cast.
Step 3: Refining (3-5 days)
The raw cast is detailed but rough. There are seam lines where the alginate was joined. Tiny surface imperfections from micro-bubbles. The bottom needs flattening so it sits properly.
This is the most painstaking part. I use fine-grain sandpaper, dental picks, and magnification to clean up every detail without losing any of the natural texture. It takes hours, spread over several days. Rushing this stage ruins the piece.
The goal isn't to make it look machine-made. A tiny bit of organic variation, a slight asymmetry, a barely-visible surface texture, is what makes it feel real. Because it is real. It's a direct copy, not a sculpted approximation.
Step 4: Sealing and finishing (2-3 days)
Once the surface is perfect, I apply several thin coats of sealant. This hardens the plaster, protects against moisture, and creates a smooth base for the finish.
Then the colour. I offer three finishes.
Classic white. Clean, minimal, works in any home. The texture and shadows do all the talking. This is the most popular choice because it matches everything.
Warm gold. A hand-painted metallic finish that catches the light. It has an heirloom quality, it looks like something that's been in the family for generations. Gold is especially popular for combined hand-and-foot sets displayed together.
Deep bronze. Darker, more dramatic. Bronze casts have a sculptural weight to them. They look incredible on a mantelpiece or bookshelf against a light wall.
Each finish takes multiple coats with drying time in between. The gold and bronze in particular need careful application to get an even, luminous surface without brush marks.
Step 5: The final piece
Two weeks after I took the mould, the cast is ready. It's sealed, finished, and completely unique. Nobody else in the world has this exact piece, because it was made from your baby's hand or foot at that exact moment in time.
I present it in a simple, elegant box with a care card. You can display it as-is, or I can arrange framing for wall mounting if you'd prefer.
What parents notice later
They always tell me the same thing. They notice new details months later. A particular crease they'd forgotten. The way the little finger curves. The exact size, which is already wildly different from the toddler now climbing the furniture.
That's the point, really. The cast doesn't change. It holds a moment that was gone almost as soon as it happened. Years from now, when your child is taller than you and their hands are bigger than yours, that tiny cast is still exactly the same.
