The egg

Eggs and spring go hand in hand, and with Easter around the corner, Studio Katja Gruijters is keen to give you some inspiration! Two fun activities with the egg, for people little and large.

Natural egg decorating

What could be more fun than a mini workshop in your own kitchen? Discover what nature has to offer when we decorate eggs with roots, herbs and onions. Let’s do this!

What you need

  • eggs (white & brown)
  • (old) tights
  • white & red onion skins
  • leaves & flowers
  • (natural) vinegar


  1. Boil the dry onion skins in a pot of water. Put enough water in the pot so you can add the eggs in later.
  2. Cook the skins for 20 minutes to release the colour. Then add a dash of vinegar.
  3. Meanwhile, prepare the eggs by wetting them a little and putting the plants on them. Put the egg with the plants on it in a stocking and knot it tightly so the plant remains in place while cooking.
  4. When the water is properly coloured, add the eggs to the pan.
  5. Let the eggs boil gently for 10 minutes.
  6. When the eggs are ready, take them out of the pan and cool them with water. This will also wash away any remaining coloured water.
  7. When the eggs have cooled down a little, remove the tights and your eggs are ready.
  8. Happy Easter!

Making pavement chalk

At Easter, of course, we eat an extra egg. But what do we do with all those leftover eggshells? Since throwing them away is a waste, we’ll tell you how to turn eggshells into real pavement chalk.

Recipe (for 5 pieces of chalk):

5 tbsp flour

5 tbsp hot water

5 tbsp ground eggshells


Pulverise the eggshells into a fine powder using a food processor, coffee grinder or blender. Put this powder into a bowl. In another bowl, mix the flour with the hot water. Add the ground eggshells and knead until a kind of pasta is formed. Turn this pasta into a long roll (2-3 centimetres in diameter).

If the pasta crumbles, wet your hands and roll again. If the pasta is too wet, add some extra flour. Divide the roll into five pieces. Let the chalk dry for 3 to 7 days. Enjoy painting your pavements!
