Our family Haunted House started out around 15yrs ago with the kids wanting a party instead of going trick or treating so we decorated the yard and everyone had fun scaring the trick or treaters. The next year we put more effort into the decorations and the next year and the next, until now we're upto around 1600 square feet of covered haunt and much more in the yard. There are a lot of props and ideas adapted from the pages of instructables. If you see your idea used THANK YOU and please post a link to your page in the comments
Step 1: Getting Started
We actually begin planning next years Haunt while we're building the current years, or at least start swapping ideas but the real work begins early in september with the erection of the portable carports which we then cover in black plastic with wire fencing on the outside for protection and to keep the plastic from blowing. The inner walls are built tinkertoy fashion from 2' pvc pipe. A HUGE tip from instructables, I remembered almost to late to use, was to cut approx 1"wide pieces of the pipe and remove about a 3rd of the resulting ring, the remaining 2/3's work a lot better than tape to hold the plastic "walls" to the pvc supports, next year we'll LOTS ready to use !
