Wear nitrile gloves to prevent fingerprints on your clay. Work on a dust-free surface, such as a silicone mat or parchment paper on a baking sheet.
Condition a medium ball of green polymer clay. Squish and knead the clay with your fingers until it's soft enough to work with. Then roll it into a ball.
Stick 2 toothpicks in the bottom of the ball to act as a handle. This allows you to work on the clay easily from any angle without running the risk of accidentally flattening or squishing it with your hand.
Step 3: Form the cactus
Use a clay knife (or craft knife) to make lines across the ball, dividing it up like a pie into 8 equal sections.
Drag a silicone paintbrush down the lines, creating indents/grooves in the clay.
Then use the silicone brush to smooth the sides of the clay. Repeat the process of defining and smoothing until you're happy with the look.
Use a toothpick or a pointed clay tool to create a line of dots going down each section of the cactus. When you're done, remove the toothpick handles and set the cactus aside for now.
Step 4: Make the flower pieces
Condition a small ball of dark pink (or another flower colour) clay.
Break the clay into 5 equal parts. Roll them into balls and then flatten them with your fingertip.
Press the flat circle onto the edge of your fingertip to round it. Then pinch one end of the petal together.
Repeat with the remaining petals. Here's what they should look like.
Form a tiny ball of yellow clay and flatten it.
Step 5: Put the flower together and bake
Press 3 of the petals together and use a toothpick or needle tool to smooth the edges against each other.
Repeat, adding the 4th petal. When you add the 5th and final petal, you can use the needle tool in the center to keep the petals together.
Press the yellow circle into the center of the flower and use a pointed tool to create texture.
Curve the edges of the petals up.
Bake the 2 clay pieces according to package directions.Our clay recommends 275F for 15 minutes per 1/4 inch thickness.
Step 6: Assemble the cactus
Once the clay has cooled, add a dot of hot glue to the bottom of the flower.
Press the flower onto the top center of the cactus.
Place a piece of dark brown felt on top of a 1 inch clay pot and cut around it. (You can also trace the pot first with chalk.)
Add glue to the bottom inside of the pot and then stuff it with a cotton ball.You can also use a ball of tin foil or crumpled paper, but make sure that the top is smooth.
Glue around the top of the cotton ball and press the felt circle into place.
Add glue to the bottom of the cactus and press it into the center of the felt. Hold it until the cactus feels secure.
Your DIY clay cactus is complete!
(Optional) Step 7: Make a clay succulent
Roll a piece of brown clay into a flat 1 inch circle.
Make 9 small 1/2 inch balls of green clay and flatten them with your fingertip.
Pinch one side of each green circle into a point, making a petal shape.
Repeat, forming 9 green petals.
Place 3 green petals on the brown clay circle, spacing them evenly around it.Use a needle tool (or toothpick) to smooth the pointed ends of the petals into the center of the brown clay.
Repeat, adding 3 more petals, placing them between the first 3.
Place the last 3 petals in the center of the succulent, overlapping the other petals a bit.
Adjust the petals, bending them slightly so they sit how you like.
Bake according to your clay's instructions.
Your clay succulent is complete!
