Gather Materials: Crayons, string, wax, jars, pots, thermometer, stirring tools, and a workspace
To begin your candle-making journey with crayons and string, it's essential to gather all the necessary materials. The first item on your list should be crayons, which will serve as the primary coloring agent for your candles. Opt for old or broken crayons, as this is a great way to recycle them. You'll need a decent amount, depending on the size of the candles you plan to make. Next, acquire some string for the candle wicks. Cotton string or twine works best, ensuring it's untreated and free from any chemicals. The length of the string will depend on the height of your jars or containers.
In addition to crayons and string, you'll require wax to create the candle base. Paraffin wax or soy wax are popular choices, available at craft stores or online. The amount of wax needed will depend on the number and size of candles you intend to make. Prepare jars or containers to hold your candles; mason jars, tin cans, or heat-resistant glass containers are excellent options. Ensure these containers are clean and dry before use. You’ll also need pots for melting the crayons and wax. A double boiler setup is ideal to prevent overheating, so have a larger pot and a smaller one that fits inside it ready.
A thermometer is crucial for monitoring the temperature of the melting wax and crayons, ensuring they don’t burn or lose their properties. Candy or cooking thermometers work well for this purpose. Stirring tools such as wooden spoons or silicone spatulas are necessary for mixing the melted crayons and wax thoroughly. These tools should be heat-resistant to avoid damage during the process. Lastly, prepare a workspace that is well-ventilated and protected with newspaper or a silicone mat to catch any spills. Ensure your workspace is stable and away from flammable materials for safety.
When gathering your materials, consider the quantity and quality of each item. For instance, if you plan to make multiple candles, ensure you have enough crayons, wax, and jars. Check that your thermometer is accurate and your stirring tools are in good condition. Organizing your materials before starting will make the candle-making process smoother and more efficient. Having everything within reach on your workspace will save time and reduce the risk of accidents.
Before you begin melting and pouring, double-check that all your materials are ready and accessible. Lay out your crayons, string, wax, jars, pots, thermometer, and stirring tools in an orderly manner. Ensure your workspace is clean and free from clutter to maintain focus and safety. Once everything is in place, you’ll be well-prepared to start creating your unique crayon and string candles. This preparation step is key to a successful and enjoyable crafting experience.

Prepare Crayons: Peel, break, and sort crayons by color for melting and mixing
To begin the process of making candles with crayons and string, the first crucial step is to prepare your crayons. Start by gathering a collection of old or unused crayons. It’s important to select crayons that are free from any paper labels, as these can burn or leave residue in your melted wax. If your crayons have paper wrappers, carefully peel them off. This step ensures a clean melt and prevents any unwanted debris from contaminating your candle mixture. Peeling the crayons might be tedious, but it’s essential for achieving a smooth and professional finish.
Once the crayons are peeled, the next step is to break them into smaller pieces. This makes it easier to melt them evenly and allows for better control when mixing colors. Use a sharp knife or a pair of scissors to cut the crayons into roughly pea-sized fragments. If you’re working with younger children, ensure they are supervised during this step to avoid accidents. Breaking the crayons also helps them melt faster and more uniformly when heated, which is crucial for creating a consistent candle texture.
After breaking the crayons, sort them by color. This step is particularly important if you plan to create layered or multicolored candles. Sorting allows you to melt specific colors separately and then layer them in your candle mold for a visually appealing result. If you’re aiming for a single-color candle, you can mix similar shades together to achieve the desired hue. For example, combine red, pink, and orange crayons for a warm, sunset-inspired candle. Sorting by color also helps you keep track of how much of each shade you have, ensuring you use them efficiently.
Once sorted, you can further organize the crayon pieces by placing them into separate containers or bags. Label each container with the corresponding color to avoid confusion during the melting process. This organization makes it easier to grab the right color when you’re ready to melt and pour. If you’re planning to mix colors, keep in mind that lighter shades can be easily overpowered by darker ones, so measure carefully to achieve the desired effect. Properly preparing and sorting your crayons sets the foundation for a successful candle-making project.
Finally, consider the quantity of crayons needed for your candle. A general rule of thumb is that one standard-sized crayon yields approximately one ounce of wax. Depending on the size of your candle mold, calculate how many crayons you’ll need to fill it. For example, a small jar might require 8-10 ounces of melted crayon wax, while a larger mold could need 16 ounces or more. Having your crayons peeled, broken, and sorted by color ensures you’re fully prepared to move on to the melting and mixing stage, bringing you one step closer to creating your unique crayon candle.

Melt Wax: Use a double boiler to safely melt crayons and wax mixture
To safely melt crayons and wax for your candle-making project, using a double boiler is the recommended method. This technique ensures that the wax mixture heats evenly and reduces the risk of overheating or burning. Start by gathering your materials: a large pot, a heat-safe bowl that fits snugly inside the pot, crayons, and any additional wax you plan to use. Break the crayons into small pieces to help them melt more quickly and evenly. If you’re using old crayons, make sure to remove any paper labels to avoid contamination.
Fill the large pot with a few inches of water and place it on the stove over medium heat. Allow the water to simmer gently—it should not boil vigorously. Place the heat-safe bowl on top of the pot, ensuring it doesn’t touch the water. This setup creates a double boiler, which provides indirect heat to melt the wax mixture slowly and safely. Add the broken crayon pieces and any additional wax (such as soy or paraffin wax) to the bowl. Stir the mixture occasionally with a spatula or spoon to promote even melting.
As the crayons and wax begin to melt, monitor the temperature carefully. Wax can become flammable if it gets too hot, so keeping the heat low and steady is crucial. If you have a candy thermometer, aim to keep the wax mixture between 160°F and 180°F (71°C to 82°C). This temperature range ensures the wax melts completely without overheating. If you don’t have a thermometer, watch for the wax to become fully liquid and smooth, with no lumps remaining.
Once the crayons and wax are completely melted, remove the bowl from the double boiler using oven mitts or potholders, as it will be hot. Allow the mixture to cool slightly before pouring it into your prepared candle container. This step is essential to prevent the hot wax from damaging the container or wick. If you’re adding essential oils for fragrance, do so at this stage, stirring well to combine.
Always prioritize safety when melting wax. Keep a lid nearby to smother any potential flames, and never leave the stove unattended. If you notice the wax smoking or bubbling excessively, reduce the heat immediately. By using the double boiler method, you can confidently melt your crayon and wax mixture, ensuring a smooth and safe candle-making process.

Prepare Wick: Dip string in wax, let dry, then attach to jar bottoms
To prepare the wick for your crayon candle, start by selecting a suitable string material. Cotton twine or braided cotton string works best due to its natural fibers, which burn evenly. Avoid synthetic strings as they can melt or produce harmful fumes. Cut the string to a length that extends about 1-2 inches above the jar or container you’ll be using for the candle. This extra length ensures the wick remains stable and functional once the candle is lit. Next, prepare a small amount of wax for dipping. You can use leftover crayon shavings or plain candle wax melted in a double boiler or microwave-safe container. Ensure the wax is fully melted and smooth before proceeding.
Once the wax is ready, carefully dip the string into the melted wax, fully submerging it. Hold the string in the wax for a few seconds to allow it to coat evenly. Slowly pull the string out, letting any excess wax drip back into the container. Lay the coated string on a sheet of parchment paper or a silicone mat to dry. This process stiffens the string, helping it stand upright in the jar and improving its burning capabilities. Allow the wax-coated string to dry completely, which typically takes about 10-15 minutes, depending on the thickness of the wax layer.
While the wick is drying, prepare your jar or container. Ensure it is clean and dry to allow the wick to adhere properly. Once the wax-coated string is fully hardened, attach one end of the string to the bottom center of the jar. Use a small dab of melted wax or a glue dot to secure it in place. Press firmly for a few seconds to ensure it adheres well. This step is crucial for keeping the wick centered and stable as you pour the crayon wax mixture later.
After attaching the wick to the jar bottom, create a simple wick holder to keep the string straight and centered. One effective method is to use a pencil or wooden skewer placed horizontally across the jar opening. Wrap the excess wick length around the pencil, ensuring the string remains taut and straight. This setup keeps the wick perfectly centered as you pour the melted crayon wax into the jar. Proper centering is essential for even burning and a professional-looking candle.
Finally, double-check that the wick is securely attached and straight before proceeding with the next steps of candle-making. A well-prepared wick ensures your crayon candle burns efficiently and safely. Once everything is in place, you’re ready to melt your crayons and pour them into the jar, completing your DIY candle project. This method of preparing the wick is simple yet effective, making it ideal for beginners and experienced crafters alike.

Pour & Cool: Pour melted wax into jars, center wicks, and let candles set
To create candles using crayons and string through the "Pour & Cool" method, begin by preparing your workspace. Gather your materials: crayons (preferably old or broken ones), string for wicks (cotton twine works well), jars or containers, a pot for double boiling, and a thermometer. Peel the paper off the crayons and break them into small pieces to ensure even melting. Set up your jars by placing a small amount of melted wax or glue at the bottom to secure the wick. Attach one end of the string to a pencil or wooden stick, which will rest on the jar’s rim to keep the wick centered.
Next, melt the crayon wax using the double boiler method to prevent overheating. Fill a pot with a few inches of water and place it on the stove over medium heat. Put the broken crayons into a heat-safe container, such as a glass measuring cup, and set it inside the pot. Stir the wax occasionally as it melts, ensuring it reaches a temperature of around 180°F (82°C). Once fully melted, remove the container from the heat and let it sit for a minute or two to cool slightly, which helps prevent the wax from shrinking too much as it sets.
Now, carefully pour the melted wax into your prepared jars. Pour slowly and steadily to avoid spills or air bubbles. Leave about half an inch of space at the top of the jar to allow for the wick and any potential settling. Immediately after pouring, gently tap the jars on the counter to release any trapped air bubbles. Center the wick by adjusting the pencil or stick resting on the jar’s rim, ensuring the wick remains straight and taut.
As the candles cool, monitor the wicks to keep them centered. The wax will begin to solidify within an hour, but it’s best to let the candles set undisturbed for at least 4 hours or overnight for optimal results. During this time, the wax will shrink slightly, creating a small dip around the wick. Once fully set, trim the wick to about a quarter inch above the wax surface for a clean burn.
Finally, test your candles by lighting them. If the wick struggles to stay lit, it may be too long or the wax might need more time to cure. Allow the candle to burn for a few hours the first time to create a “memory ring,” which helps prevent tunneling in future burns. With these steps, you’ll have beautifully crafted, colorful candles made from crayons and string, ready to brighten any space.
