You probably do a great job of decorating the outside of your house for Halloween. I know I do, but a problem that I had is that when the trick or treaters rang the doorbell to get candy and the front door was opened, all of the Halloween themeing stopped. This year I fixed this problem and continued the Halloween atmosphere inside when the front door was opened.

In this Instructable, I am going to show you how to continue a really good Halloween atmosphere inside of your house. At the bare minimum, all you need are some white sheets, something to hang them with, an oscillating fan, and a black light, and then youâre ready to goâ¦

Step 1: Hang the Sheets...

Hang the sheets. I hung my sheets using a system that was bought at an Ikea. It consists of two anchors that go into the walls, and a metal cable that goes between the two anchors. I strung the sheets along this cable and made sure everything was nice and secure.

Step 2: Set Up Black Light

Set up the black light. The way my house is setup, I have the front door open up to a raised tile area, and then off to the side, there is a lower computer room. It is in this room where I put the black light. This way, the trick or treaters couldnât actually see the black light bulb itself, but they could see the glow it produced on the white sheets. I always feel it is very bad for your atmosphere when setting up a haunted house to allow trick or treaters to see black lights. They hurt your eyes. The ultraviolet light is actually eating away layers of anything that glows. Thatâs why black lights making things glow, and if you notice, the whites of your eyes glow in black light. I donât like looking at them for this reason, and besides it is better to have the glow coming mysteriously from some unknown source rather than from a seen light fixture.

Step 3: Fan

Set up the fan. Put the oscillating fan near the black light behind the sheets. Plug it in and turn it on. This produces the effect of the sheets blowing in the wind. With the glow and the motion of the wind, this looks really nice.

Step 4: Add Your Personal Touch...

Add your own personal touch. I have an eye theme going through my haunted house. There are eyeball creatures that watch you as you walk through to ring the doorbell. I thought I would add some eyes on the inside too. I have a piece of colored glass hanging up that represents an eye. Iâm not sure where this originated from, since Iâve seen it claimed to be a Native American tradition, a Mexican tradition (although that could still be Native American), and an Indian (from India) tradition. Wherever this originated from, you are supposed to hang it by your front door and it should keep out any evil spirits. Although my paper machie spirits outside will be coming in anyway after Halloween.

I also have a wonderful painting of an eyeball that is also hanging in this raised area by my front door. No one really notices it, but itâs still there continuing the Halloween theme.

Depending on how your house is set up, and what your Halloween theme is, do this to your own liking. This is the way I did it, but by no means is it the only way to do this. Get creative!
