How to make a baby handprint cast in plaster — complete guide

The first weeks go by so fast. You know you'll forget just how tiny those little hands were — and that's exactly why a plaster handprint is one of the most precious memories you can create with your baby.

The good news: it's much simpler than you think. No artistic skills needed, no big budget. Just 20 minutes, a little patience, and this guide.

What you'll need

• Plaster of Paris (250g is enough)
• Flexible silicone mold 15×15 cm
• Lukewarm water
• Mixing bowl (disposable is fine)
• Wood or plastic spoon
• Acrylic paint (to decorate after drying)
• Damp cloth

Total budget: under €15 / $18. Everything is available at the pharmacy, stationery store, or Amazon. To avoid hunting for each item, this Amazon kit includes everything{target="_blank" rel="noopener"}.

Preparing baby and your space

Choose a moment when baby is relaxed — after feeding and a bath, never when they're hungry or tired. The session takes 5 minutes max.

Prepare everything in advance: once the plaster is mixed, you'll have about 10 minutes before it starts to set.

• Lay down newspaper under your work area
• Keep a damp cloth handy to clean baby's hands
• Ask another adult to hold baby if possible

Step-by-step instructions

1. Mix the plaster Pour 3 parts plaster to 1 part water. Mix slowly until you get a thick yogurt consistency.

2. Pour into the mold Pour to about 2 cm deep. Gently tap the mold on the table to release air bubbles.

3. Press baby's hand Gently place baby's hand, palm down, in the center. Press lightly and evenly for 15–20 seconds. Remove with a slow, smooth motion.

4. Clean immediately Plaster is non-toxic but can dry out skin. Clean with the damp cloth. If plaster is stuck in creases, rinse with lukewarm water.

Drying and finishing touches

Plaster sets on the surface in 30 minutes but needs 24–48 full hours before demolding. Don't rush — an undercooked print breaks easily.

Once fully dry, you can:

• Paint the handprint white and the background in color (soft pink, terra)
• Add the first name and birth date with a thin brush
• Apply gloss varnish for protection
• Frame in a RIBBA IKEA frame 23×23 cm{target="_blank" rel="noopener"}

My tips for success

Secret #1: a fully relaxed hand makes all the difference. If baby's fingers are curled, wait until they're sleepy or gently tickle their palm to get them to open their hand.

If the first try doesn't work: plaster is cheap. Wait for the first one to fully dry, mix a second batch, and try again. Baby is often more cooperative the second time.
