If you don't mind spending a lot of money or doing a lot of prep work, then Rockett St. George has a wallpaper you might be interested in.
I would have told you about this gem last night, but we lost our internet connection for the evening (and cable...and phone. The horror!).
"The signature paper featuring skulls in a reflective bronze, deep pile velvet on a incredible light-catching, iridescent base, using horribly expensive ink which changes colour as you walk past it - through reds, greens, blacks and golds - like an oil slick."
I was recently given a generous offer by someone: decorate a store for Halloween (using my private collection of decorations) and they will sell my items for two weeks.
I've never decorated a store, so I had to come up with some logical guidelines pretty quick for myself:
Keep everything up and out of the way
Don't detract from the products or block them
Items must be fairly small (shelves were 1 foot deep)
Set up and take down must be easy (and not messy especially since it's during store hours)
Choose items that match the style of the store and are LESS likely to offend
That last point was even more important when I found out they were going to be inspected by a bigwig in the company in the next week. While the employees were excited for some bloody severed heads and cocoon victims, I didn't think the manager of the store (or the big suits coming to inspect the store) would be so keen.
The folks over at Decor It Yourself (www.threadbanger.com) have put together a fun little instructional video on how to add a little Hitchcock to your Halloween party.
