Concrete mix (smooth grey, 10 lbs)

Begin by designing your geometric planter mold. Use a ruler and pencil to draw angular shapes on the cardboard, ensuring they will fit together to form a 3D shape.

Carefully cut out the shapes using a utility knife. Score the edges lightly for easy folding.

Assemble the cardboard pieces into the desired geometric shape, securing them with tape to form a sturdy mold.

Spray the inside of the mold with cooking spray to ensure easy release of the concrete once it sets.

Mix the concrete in a bucket according to the package instructions, adding water gradually until you reach a smooth, pourable consistency.

Slowly pour the concrete mix into the mold, ensuring no air bubbles are trapped by gently tapping the sides of the mold.

Allow the concrete to cure for 24 to 48 hours, depending on the thickness of your planter.

Once the concrete is fully set, carefully remove the cardboard mold.

Smooth any rough edges with fine-grit sandpaper for a polished finish.

To customize your planter, consider using colored concrete pigments to match your interior decor or outdoor setting. You can also experiment with different geometric shapes or sizes to create a collection of planters in various styles. For added texture, consider embedding small stones or tiles into the wet concrete for a unique, decorative touch.
