Halloween Mason Jar Crafts: Tutorial on how to make a creepy light up spider jar for halloween decor, center pieces or scary bathroom night light

To create your light-up spooky mason jar you will need:

Mason jars (I prefer the ones with no BALL on them for Decor, otherwise you will have to see branding)
Spiders
Fake Spiderweb
Black Nail Polish
Hot glue
Tea lights (Flameless)

The first thing with a mason jar is that you need to age it to make it creepy. One of the best ways I have found to do this is to use nail polish. Simply pour in some black nail polish and swish the water around so it spreads to a flat layer of black.

Now dip your jar in on the bottom and then turn around and do the top. This will leave the middle of the jar clear for spider viewing but give you some good age on the top and bottom of the jar itself.

While your jar is drying, put a flameless tea light on the bottom of your jar. I used tongs to place mine. Then spread the fake spider web into the jar, securing it with a few drops of hot glue inside the lid or top and bottom of the jar.

You can use a straw or stick to push it down all the way to secure it.

Now drop spiders and affix them with hot glue in strategic spots.

For this set, I loved how it looked but decided to add an additional creepy factor by looping a few times with more fake spider web around it in thin areas.

The first picture is my light-up jar and it looks equally awesome in a dark room as well as in bright light.

The second smaller jar does NOT have a light in it so the focus is more on the actual Halloween decor itself.
