How to Make DIY Giant Birthday Candles

Step 1 — Paint the mailing tubes
Start by painting your mailing tubes with white paint. This helps cover any marks or discoloration and gives them a clean, “real candle” look. If your tubes are already bright white, feel free to skip this step.

Step 2 — Create the cone top
While the paint dries, trace a circle onto white cardstock. Cut out the circle, then remove a small wedge so you can roll it into a cone shape.

Step 3 — Form the candle top
Roll the cardstock into a cone that fits snugly on top of your tube. Trim as needed for the perfect fit.

Step 4 — Make the wick
Cut a piece of rope about 5-inches long. If the ends tend to fray, wrap a small piece of tape around them to keep things neat.

Step 5 — Attach the wick
Hot glue the rope to the center of the mailing tube lid to create the “wick,” then place the lid back onto the tube.

Step 6 — Adjust the cone
Cut a small opening at the tip of your cone so it fits around the rope. Once it sits properly, hot glue the cone closed.

Step 7 — Assemble the candle
Apply hot glue around the rim of the tube and attach the cone top, pressing gently until secure.

Step 8 — Finish the wick
Remove any tape from the rope and add a small amount of hot glue to the ends to prevent fraying.

Step 9 — Paint the stripes
Use the natural spiral line on the tube as a guide to paint your stripes. Let each stripe dry before adding another to avoid smudging.

Tips for the Best Results

Use thicker cardstock for durability
Mix heights and colors for a playful look
Add glitter or metallic paint for extra shine
Make flames by cutting flame shapes from tissue paper (layer yellow, orange, and red for dimension). Twist slightly and glue them into the center of each candle.
