Today, I will demonstrate how to easily create a simple plaster plant pot.

Supplies

To begin with, it requires some materials to make the plant pot.

- 75cm by 75cm polypropylene

- A pencil (An Eraser most likely)

- A ruler

- A safety cutting ruler

- A protractor

- A cutter

- A scotch tape

- 6 cups of plaster powders

- 4 cups of water

- A spatula

- A bucket

Step 1: Drawing the Faces of the Mould

Using a ruler, draw 4 trapezoids with 12 cm on the each sides, 5 cm on the base and draw a line by connecting the end of each sides. Then draw a 5 cm by 5 cm square for the base of the mould.

Step 2: Creating the Mould

Then slowly using a safety cutting ruler, cut the polypropylene by following the lines drawn, and with the scotch tape, tape the faces to make the mould.

Step 3: Drawing the Faces of the Core

As same as step #1, draw 4 trapezoids with 9 cm on the each sides, 3 cm on the base and draw a line by connecting the end of each sides. Then draw a 3 cm by 3 cm square for the base of the mould.

Step 4: Creating the Core

After outlining the face, use a safety cutting ruler to cut the polypropylene by following the lines drawn, and with the scotch tape, tape the faces to make a trapezium pyramid core.

Step 5: Making Plaster

Now, you have to make plaster. Get 4 cups of water and pour it into a bucket. Next step is to get 6 cups of plaster powder. Start mixing it with the water until the solution turns to a dense liquid. If it doesn't become as dense, you can try adding 1 to 2 cups of plaster powder more.

Step 6: Pouring the Plaster Inside the Mould

Bring the mould and pour the plaster inside leaving 2 to 3 cm space on top to avoid spilling when the core gets put in.

Step 7: Putting Core Inside the Mould

After pouring the plaster, slowly push the core through the plaster. The core most likely has to be put in the centre of the mould and should not reach the ground as then it will create a big hole, but needs to be a little above from it so that the plant has enough space to live in.

Step 8: Waiting...

Wait for the plaster to dry for at least 30 minutes, and get it out of the mould and remove the core carefully so that the plaster doesn't get damaged.
