Many kits are sold in children's stores to make prints of children's pens and legs. They are usually quite expensive. In this case, the casts can be made independently without purchasing a special mass for this.
The little ones' arms and legs are so tiny and touching that I would like to leave their casts as a souvenir. To do this, you can use one of the following recipes:
1. The prints can be left in plasticine or modeling mass. This method is suitable for a baby over one year old. Before that, it is quite difficult to knead the mass so well that a light touch of a child's hand or leg leaves a strong imprint.
2. Perhaps the most popular way to make an impression of a handle or leg is by using salt dough. Mix 1 cup flour, 1 cup salt, 2 tbsp. tablespoons of oil and ½ glass of water. Knead into a tight, homogeneous dough. Add a little more water if necessary to make the dough more pliable. Roll out the dough into a 2 cm thick layer and form a shape (it can be a circle, square or, for example, a heart). Place your child's pen or leg on the dough and let it sit for a few seconds. Then carefully remove the handle or leg. If the impression is not very good the first time, roll out the dough again and start over. Make a hole for the stud or ribbon. Leave the resulting print to dry at room temperature for 2-3 weeks. After that, the cast can be painted with acrylic paints and varnished. Instead of drying for a long time, you can bake the print in the oven. However, in this case, the dough may rise and the impression will be distorted.
