50 Best Scary Halloween Decorations And 5 Great Theme Ideas

I LOVE these holiday projectors! Have you seen them? You can project a high res moving scene onto a window so that everyone outside can see it.

They have a handful of default Halloween & Christmas scenes installed. And, you can download many more on the companies site. These start for as low as $40.

I'll definitely be adding one to our house for the upcoming holiday season!

So, you can get this one as a CD, MP3, and streaming. That makes it so easy to add spooky music and sound effects to your front porch or party. And, the streaming version is FREE with your Amazon Prime membership.

A fog machine can make any cheap Halloween decoration instantly scary. And the fog acts as a great filler, connecting the decorations together in a polished way.

Like a fog machine, cobwebs are a great filler that makes your Halloween scene look bigger and connected. This one comes with spiders too!

Here's another gauzy filler that helps make your decorations look more pulled together and complete.

If you're not a fan of cobwebs, go for black creepy gauze as a filler.
