These ghostly glowing Halloween mason jars are an easy way to turn a handful of inexpensive supplies into wonderfully creepy Halloween decorations.
Clear glass jars are filled with soft white cobwebs, crawling black spiders, and tiny warm lights to create the appearance of something mysterious glowing from inside an abandoned spider nest.
Best of all, you can make several jars in different sizes and group them together just like the display shown here. Once darkness falls, the warm lights shine through the wispy webbing and transform ordinary jars into miniature haunted lanterns.
Use them on a Halloween party table, fireplace mantel, entryway console, kitchen counter, or as part of a larger Halloween decorations display.

🎃 Supplies You’ll Need
To recreate the glowing jars, gather:
- Clear mason jars or clean recycled glass jars
- Battery-operated LED fairy lights or LED tea lights
- White faux spider-web material
- Small black plastic spiders
- Scissors
- Tweezers, a pencil, or a wooden skewer
- Clear craft glue or a hot glue gun, optional
- Thin black thread or fishing line, optional
- Black ribbon, twine, or Halloween ribbon, optional
Using jars in several different heights and widths makes the finished collection much more interesting.
You do not necessarily need traditional mason jars, either. Empty pasta sauce, jam, condiment, or food jars can work beautifully once the labels and adhesive have been removed.
👻 Step 1: Clean and Prepare the Jars
Wash the jars and remove any labels, glue, dust, or fingerprints.
Allow them to dry completely before adding the decorations.
Clear glass works especially well for this project because you want the light, white webbing, and black spiders to remain visible.
For an arrangement similar to the inspiration image, leave the glass mostly undecorated rather than covering it with paint. The simplicity helps the spiders stand out against the glowing white interior.
🕸️ Step 2: Create the Wispy Spider Webs
Take a very small amount of faux spider-web material and gently stretch it between your fingers.
The secret here is less is more.
Instead of stuffing the jar completely full, pull the material until it becomes thin, airy, and almost transparent.
Place some around the bottom of the jar and stretch additional strands upward along the glass.
Use tweezers, a pencil, or a wooden skewer to move the webbing into position.
Try to create:
- Thin strands across the glass
- Small fluffy areas around the bottom
- Open spaces where light can shine through
- Uneven wisps that resemble an old abandoned web
The imperfect arrangement is what makes these jars look convincing.
If you enjoy spider-themed projects, you can also make our Spooky Construction Paper Spider Webs to decorate the wall or table behind your glowing jars.
🕷️ Step 3: Add the Spiders
Now invite a few creepy residents into the jars.
Position small black spiders directly against the white webbing so their silhouettes are easy to see.
Place some near the glass and others farther inside the jar to create depth.
For a collection of several jars, vary the placement. One jar might have a large spider in the center, another could have several tiny spiders crawling along the sides, and another might feature a spider dangling from above.
Make a Hanging Spider
For an extra-creepy effect, tie a small spider to a piece of thin black thread or fishing line.
Attach the other end near the top of the jar so the spider appears to be lowering itself into its web.
You can also glue a spider to the outside of the glass to make it look as though one escaped.
✨ Step 4: Add the Ghostly Glow
Carefully place a small strand of battery-operated LED fairy lights inside the jar.
Warm white or amber lights produce the cozy orange glow seen in the inspiration image and look especially good against white webbing.
Arrange the lights loosely throughout the web rather than placing them all at the bottom.
You want small pockets of light to appear throughout the jar.
Another easy option is a battery-operated LED tea light. Simply place it near the bottom and arrange the webbing around it.
Important: Do not use a real candle or open flame inside jars containing faux cobwebs, cotton, paper, plastic spiders, or other craft materials. Stick with battery-operated LED lighting for this project.

🕯️ Step 5: Hide the Battery Pack
If your fairy lights have a small battery pack, tuck it behind the jar or arrange the webbing so it is less noticeable.
Depending on the size of the pack, you may also be able to conceal it near the top of the jar.
Try to keep the switch accessible so you can easily turn the lights on and off.
Once the jars are arranged together, battery packs are surprisingly easy to disguise behind the taller jars.
🖤 Step 6: Add Finishing Touches
The simple clear-glass design already looks wonderfully spooky, but you can embellish the jars if you like.
Try adding:
- Black ribbon tied around the neck
- Black-and-orange baker’s twine
- Tiny skeleton charms
- Miniature bats
- Black lace
- A dangling spider
- Small “Beware” tags
- A miniature skull
- Faux moss
- Tiny plastic bones
Keep embellishments relatively restrained if you want the glowing web-and-spider effect to remain the star of the project.
🕸️ How to Make the Jars Look Like the Inspiration Photo
For the closest recreation of the pictured display, concentrate on four details.
Use several jar sizes.
A mixture of tall and short jars creates a much more interesting centerpiece than identical containers.
Keep the webbing white and fluffy.
The pale material captures and diffuses the warm glow beautifully.
Use simple black spiders.
Their dark silhouettes create strong contrast against the illuminated webbing.
Choose warm lights.
Warm white or amber LED lights produce the eerie orange-gold glow that makes the jars look almost like tiny supernatural lanterns.
Place the jars fairly close together once finished. Their overlapping pools of light will make the entire arrangement feel like one Halloween centerpiece.
🎃 Fun Variations to Try
Once you’ve mastered the basic glowing spider jar, make a few different versions.
👀 Glowing Eyes Jar
Cut pairs of sinister eyes from black cardstock and position them against the inside of the jar.
When the lights come on, the eyes appear to emerge from the glowing mist.
👻 Ghost Jar
Skip the spiders and place tiny paper or gauze ghosts among the white webbing.
Use cool white lights for a more spectral effect.
🪦 Mini Graveyard Jar
Add a little faux moss to the bottom along with miniature tombstones, skeleton pieces, and dim lights.
🧙 Witch’s Jar
Swap the white cobweb for black or purple fibers and add miniature potion bottles, bats, or witch charms.
Purple or green LEDs can give this version a magical glow.
🕷️ Giant Spider Jar
Place one oversized spider prominently against the front glass and surround it with thick webbing.
This simple version can look especially dramatic when viewed from across a dark room.
🎃 Pumpkin-Glow Jar
Use orange fairy lights and scatter a few miniature pumpkins around the base.
The result is warmer and more whimsical than the classic spider version.
👨👩👧 Can Kids Make These Halloween Mason Jars?
Yes—with age-appropriate adult supervision.
Children can help:
- Stretch the spider webs
- Choose the spiders
- Arrange decorations
- Position battery-operated lights
- Select ribbon and embellishments
Adults should handle hot glue guns, difficult cutting, and anything involving breakable glass with younger children.

🏠 Ways to Display Your Glowing Halloween Jars
These lanterns are small enough to fit almost anywhere.
Try displaying them:
- Across a fireplace mantel
- On an entryway table
- Beside a bowl of Halloween candy
- Along a party buffet
- On a bookshelf
- In a Halloween centerpiece
- On a covered porch
- Around a collection of pumpkins
- Beside a spooky wreath
- On a kitchen island
- In a Halloween window display
For the strongest effect, arrange three to five jars of varying heights together rather than scattering individual jars throughout the room.
Add pumpkins, black candles, ravens, skulls, or additional faux cobwebs around the group to create a complete scene.
♻️ Turn Recycled Jars Into Halloween Decorations
One of the nicest things about this project is that you don’t necessarily need to buy new containers.
Save attractive glass jars throughout the year and turn them into Halloween lanterns when October arrives.
Making decorations from materials you already have can also inspire other projects. Our 5 Easy Halloween Toilet Paper Roll Decorations offer another inexpensive way to turn everyday materials into spooky seasonal décor.
💡 Tips for the Best Glowing Effect
A few small adjustments can make a big difference.
- Stretch the webbing very thin before putting it inside.
- Keep at least some of the spiders close to the glass.
- Use several jar sizes.
- Hide the battery packs behind the display.
- Turn off bright room lights when displaying the jars.
- Mix large and small spiders.
- Avoid overfilling the jars.
- Place a few lights near the front of the jar.
- Create slightly different designs in every jar.
- Group the finished jars closely together.
If one jar doesn’t look quite right, simply pull everything out and rearrange it. There is no permanent positioning required unless you choose to glue the decorations.
❓ Frequently Asked Questions
What kind of lights should I use in Halloween mason jars?
Small battery-operated LED fairy lights or flameless LED tea lights are ideal for this craft. Warm white or amber lights create the classic orange Halloween glow, while purple, green, or cool white lights can produce completely different effects.
Can I use cotton balls instead of fake cobwebs?
Yes. Pull cotton balls apart into extremely thin wisps before placing them inside the jar. Faux cobweb material generally creates longer strands, while pulled cotton tends to produce a softer, cloudier appearance.
Can I use real candles?
No. Because these jars contain decorative fibers and plastic craft materials, use battery-operated LED lights rather than an open flame.
Do the mason jars need lids?
No. They look just as good without lids, and leaving them open can make it easier to arrange the lights and access the battery pack.
Can I make these without mason jars?
Absolutely. Clean recycled glass jars work well. Mixing different shapes can actually make your finished display more interesting.
How many jars should I make?
Three to five jars create a nice tabletop arrangement, but you can make as many as you like. A mixture of taller and shorter jars creates the most visually interesting display.
🧡 A Simple Halloween Craft with a Spooky Glow
