Step-by-step method and video

Salt dough - is it difficult? No way! All you need is flour, water and salt (of course!) Salt dough is a basic craft recipe that even little kids can make. And what could be more fun for your toddler or preschooler than making a dinosaur fossil out of their dough?
  • Morning or afternoon project
  • 12 tbsp plain flour, 5 tbsp table salt, 5 tbsp water, rolling pin, biscuit cutters (or a knife) and a small toy dinosaur
  • 2+

First, make the salt dough

  1. Put 12 tbsp plain flour and 5tbsp table salt into a bowl and stir.
  2. Add approx 5tbsp water and use your hands to bring the mixture into a dough. The mixture should be quite dry. If it’s too dry, add a splash more water. If it’s too wet, add a little more flour.

Remember Children can help you with the measuring, pouring, stirring and mixing.

Handy tip The salt in the dough can be quite drying to your hands. If you have sensitive skin, you might want to put on a pair of marigolds!
