3D casts capture every wrinkle, crease, and tiny fingernail in stunning detail. They’re one of the most impressive baby keepsakes you can create.
DIY vs Professional
DIY kits (£15–£40): Alginate moulding powder and plaster. Good results with practice. Expect 2–3 attempts.
Professional service (£80–£250): An expert takes the mould and produces a flawless cast, often painted in silver, gold, or bronze.
DIY Process
- Mix alginate with water to a smooth paste. Pour into a container.
- Gently submerge baby’s hand or foot. Hold still for 30–60 seconds until set.
- Carefully remove the hand, leaving a perfect mould.
- Mix plaster and pour into the mould. Tap to remove bubbles.
- Once set (several hours), peel away the alginate to reveal the cast.
Best Age
Newborn to 6 months is ideal — small enough to be adorable, sleepy enough to cooperate. After 6 months, they start grabbing the alginate and it becomes a wrestling match.
Display Ideas
Mount on a base, display in a shadow box, or place on a shelf alongside a photo from the same age. A matching hand and foot pair is particularly impressive.
