Looking for an eye-catching Halloween decoration to welcome trick-or-treaters or set the mood for your spooky gatherings? A DIY Halloween Pumpkin Arch is the perfect way to bring a festive and eerie vibe to your entrance. The best part is, you don’t need to carve real pumpkins or deal with the mess—they can all be plastic! Let’s dive into this easy, budget-friendly DIY project that will surely elevate your Halloween décor.
Materials You’ll Need:
- Plastic pumpkins (you’ll need about 20-30 depending on your arch size)
- PVC pipe (for the arch frame)
- Wire or zip ties (to secure the pumpkins)
- Drill with a hole saw bit (for drilling holes in the pumpkins)
- String lights (optional for extra glow)
- Rebar stakes (to anchor the arch into the ground)
- Spray paint (optional, if you want to customize pumpkin colors)
- Hot glue gun (for additional decorations like faux leaves or spiders)
Step 1: Gather Your Plastic Pumpkins
Plastic pumpkins are perfect for this project because they’re lightweight and reusable. You can find these pumpkins at most dollar stores, craft stores, or online. Decide how many you’ll need based on the size of your arch. For a standard-sized arch, you’ll likely need around 25-30 pumpkins of varying sizes for a full look.
If you want to personalize the colors, now is the time to spray paint the pumpkins to match your Halloween theme (black, white, or classic orange).
Step 2: Build Your PVC Pipe Arch Frame
The next step is to construct the framework for your arch using PVC pipe. PVC is affordable, lightweight, and sturdy enough to support your pumpkin display. Here’s how to create the frame:
- Measure and cut two pieces of PVC pipe for the sides of the arch.
- Cut a curved section for the top of the arch—this can be done using flexible PVC pipe, or you can use straight pieces connected with elbow joints to form a curve.
- Secure the frame into the ground using rebar stakes. Simply hammer the stakes into the ground and slide the PVC pipes over them for a stable base.

Step 3: Prepare the Pumpkins
To attach the pumpkins to the PVC pipe, you’ll need to drill holes in the bottom and top of each pumpkin. Using a drill with a hole saw bit (about 1 inch in diameter), carefully cut holes large enough for the PVC pipe to pass through.
If you want to add string lights, now is a great time to place them inside the pumpkins. You can feed the lights through the holes you just drilled, allowing them to shine through the pumpkins for a glowing effect at night.

Step 4: Thread Pumpkins Onto the PVC Pipe
Once the holes are drilled, start threading the pumpkins onto the PVC pipe. Slide them through the top and bottom holes until they are arranged along the arch frame. Alternate pumpkin sizes and colors to create a balanced and visually appealing display.
Step 5: Secure the Pumpkins
After all the pumpkins are on the PVC pipe, use wire or zip ties to secure them in place. Wrap the wire or ties around the pumpkin stems and the PVC pipe so they don’t shift or move over time.
If your pumpkins feel loose or unstable, use a hot glue gun to add extra security by gluing them directly onto the PVC pipe.
Step 6: Add Final Decorations
To make your pumpkin arch even more festive, you can add additional Halloween-themed decorations. Use your hot glue gun to attach faux leaves, spider webs, plastic spiders, or bats to the pumpkins or the frame itself. This will add more texture and interest to your arch.
Step 7: Illuminate the Arch (Optional)
If you added string lights inside the pumpkins, simply plug them in, and watch your arch come to life! The glowing pumpkins will give your Halloween arch a magical effect at night. You can also wrap additional string lights around the frame of the arch for extra brightness.
Step 8: Secure the Arch
Once your pumpkin arch is fully decorated, make sure it’s secure. If needed, add extra rebar stakes to the sides or use sandbags at the base for more stability. You don’t want your beautiful creation blowing over on a windy day!
Conclusion
With just a few simple materials and some creativity, you can create a stunning DIY Halloween Pumpkin Arch that will wow your guests and neighbors. This project is not only fun to make, but it also gives your home a festive and spooky touch without the hassle of real pumpkins. Happy Halloween, and enjoy your new décor!
