Let’s dive into the process of crafting these stylish and functional concrete bookends.

Materials You’ll Need

Before you begin, gather all the necessary materials. Having everything on hand will streamline the process and ensure a smooth crafting experience.

• Heavyweight Cardboard: This will serve as the mold for your bookends. Choose a sturdy cardboard to withstand the weight of the concrete.
• Strong Tape: Masking tape or Duck Tape are ideal for securely assembling the cardboard molds.
• Rapid Set Concrete Mix: This type of concrete sets quickly, reducing the waiting time.
• Bucket: For mixing the concrete.
• Stir Stick or Wooden Spoon: To thoroughly mix the concrete and water.
• Water: To create the concrete mixture.
• Two Containers: These will hold the bookends upright while the concrete sets. Consider using plastic containers or sturdy boxes.
• Beans or Weights: To stabilize the containers and prevent them from tipping over.
• Cooking Spray: To prevent the concrete from sticking to the cardboard molds.
• Boxcutter or Sharp Blade: To cut the cardboard into the desired shapes.
• Level: To ensure the bookends are perfectly plumb (vertical) during the setting process. You can use a physical level or a level app on your smartphone.

Step-by-Step Instructions

Follow these detailed instructions to create your own stunning geometric concrete bookends.

1. Design Your Shape

Start by selecting a shape for your bookends. A multi-sided pyramid offers a visually appealing and structurally sound design. Creating a paper template first can be helpful for accurately cutting the cardboard mold. Remember to designate one side of your shape as the “book side,” ensuring it’s plumb for optimal book support.

2. Cut the Cardboard Pieces

Using the cardboard and a sharp blade, carefully cut out the individual planes of your molds. For a multi-sided pyramid, this will involve cutting multiple triangles of varying sizes for each bookend. Precision is key to achieving a clean and professional look.

3. Assemble the Molds

Once all the sides are cut, generously tape the cardboard pieces together to form the molds. Don’t hesitate to use plenty of tape, as the concrete will be heavy and exert pressure on the mold. Ensure all seams are securely sealed to prevent leaks.

4. Apply Cooking Spray

After assembling the molds, spray the insides with cooking spray. This will create a barrier between the cardboard and the concrete, preventing them from bonding and making it easier to remove the molds later.

Important Tip: Avoid spraying the cardboard before assembly, as it can make the pieces slippery and difficult to handle.

5. Secure the Molds

Place the beans or weights in the containers to provide stability. Position the molds upside down in the containers, embedding them in the beans. Use a level to meticulously ensure that the book sides are perfectly plumb. This step is crucial for creating functional bookends that will hold books upright.

6. Mix the Concrete

Prepare the concrete mix according to the manufacturer’s instructions. The ideal consistency should be somewhere between thick and runny. A properly mixed concrete will flow smoothly into the molds without being too watery.

7. Pour and Set

Carefully pour the concrete mixture into the molds, filling them completely. Gently tap the molds to release any trapped air bubbles. Allow the concrete to set and dry overnight. Resist the temptation to check on them too soon, as disturbing them during the setting process can compromise their integrity.

8. Remove the Molds

Once the concrete is completely dry, carefully remove the cardboard molds from your new bookends. You may need to use a knife or blade to gently score the cardboard along the edges to facilitate removal. Be patient and avoid applying excessive force, as this could damage the concrete.

Optional: Before using your new bookends, you can wash them with soap and water to remove any residual oil from the cooking spray.
