The method of making Christmas tree plasticine is as follows: 1. Knead the green plasticine into a triangle to make the tree body, and roll the brown plasticine into a cylinder to make the trunk.

2. Use toothpicks to connect the tree body and trunk, poke small holes randomly on the tree body, knead spherical particles of various colors to make colorful fruits, and evenly decorate the tree.

3. Roll a few long linear strips, coil them around the tree body, make a five-pointed star, and fix it on the top of the tree with toothpicks.

Today, the material and craftsmanship of plasticine have changed a lot. Unlike before, plasticine cannot be mixed in color, cannot be reused, and is relatively rough and hard.

The upgraded version of plasticine is called "colored clay", and the higher-end version is called "ultra-light clay". The representative one is "Oak clay". Plasticine can be divided into industrial plasticine and ordinary plasticine for children to play with.

The composition of plasticine: 1. It does not contain preservatives. Liquid paraffin is used as the oily component, which is non-toxic, odorless and safe to use.

2. It hardly evaporates to dryness at room temperature, so it has good long-term stability.

3. Easy to process, use a non-stick bamboo knife at high temperatures and will not stick to your hands.

4. Adding metal soap, etc. can not only improve the affinity between inorganic fillers and oil components, but also improve the viscosity of oil clay.

5. Liquid paraffin is added to the oil component to improve the plasticity of the oil clay.

Softening method: Use a wet towel to cover the dry plasticine. It won't take half a day before it can be used again. Use a small brush dipped in water to brush the surface of the plasticine, a small amount several times. Put the plasticine into a plastic bag.

, soaked in warm water for half a day, it will become soft.

First spray some water on the plasticine, then cover it and let it dry in the sun for a day, and it will soften.

If that doesn't work, repeat the above steps a few more times.
