Step 1: Prepare the Cardboard Tube
Remove any paper or glue residue from the cardboard tube.
Flatten any dents by gently reshaping the tube with your hands.
Trim both ends with scissors so they are straight and even.
If the tube is taller than about 4½ inches, trim it to your desired height.
Step 2: Shape the Cactus
Using scissors, round the top corners of the cardboard tube.
Trim gradually until the top resembles the curved shape of a cactus.
Lightly sand any rough edges if needed.
Step 3: Paint the Base Color
Apply one coat of light green acrylic paint over the entire cardboard tube.
Allow it to dry completely.
Apply a second coat for full coverage.
Let the paint dry for another 20–30 minutes.
Step 4: Add Cactus Texture
Using medium green paint, paint several long vertical stripes from the top to the bottom.
Blend the edges slightly while the paint is still wet.
With dark green paint, add thinner lines between some of the larger stripes.
This creates the natural ridges found on real cacti.
Allow the paint to dry completely.
Step 5: Make the Side Arms
Roll two equal balls of green air-dry clay.
Shape each into a small oval cactus arm.
Flatten the side that will attach to the cactus body.
Allow the clay to firm up slightly before attaching.
Step 6: Make the Flowers
Roll tiny pink clay balls.
Flatten five small petals for each flower.
Arrange the petals into a flower shape.
Roll a tiny yellow ball for the flower center.
Press it gently into the middle.
Make one flower for each cactus arm.
Step 7: Attach the Arms
Apply hot glue to the flattened side of each cactus arm.
Press one arm onto each side of the cardboard cactus.
Hold for about 30 seconds until secure.
Allow the glue to cool completely.
Step 8: Attach the Flowers
Glue one pink flower onto the top of each cactus arm.
Press gently until the glue sets.
If desired, add tiny painted dots around the flower centers for extra detail.
Step 9: Draw the Face
Using a black paint marker:
Draw two large oval eyes.
Inside each eye, add a small white highlight.
Draw a tiny smiling mouth beneath the eyes.
Add two pink circles on the cheeks using pink paint or blush.
This gives the cactus a cute kawaii expression.
Step 10: Prepare the Pot
Fill the flower pot with floral foam, crumpled paper, or modeling clay.
Leave about ½ inch of space below the rim.
Add hot glue over the filler to hold it in place.
Step 11: Attach the Cactus
Apply a generous amount of hot glue to the bottom of the cardboard cactus.
Press it firmly into the center of the pot.
Hold it upright until the glue fully hardens.
Step 12: Finish the Pot
If desired, decorate the flower pot by:
Painting it terracotta, white, or pastel colors.
Wrapping it with twine.
Adding tiny painted flowers or dots.
Gluing miniature pebbles around the cactus base.
These details make the finished craft look more polished.
Step 13: Display
Place the finished cactus on:
A desk
Bookshelf
Windowsill
Office workspace
