The best place to start is by looking around your own haunted mansion, or your sweet little cottage, and find things you already have to embellish and build upon. What do you do you see that you can transform into something else, or add a few touches to make it a part of the season? Old jars, books, fabric, paper, photos, etc., and I bet you can think of a bunch more! Think of new ways to display your old decorations with some new (old) things you have somewhere else in the house.
Since I've been using black and white and damask for a long time, it was the perfect way to start my Halloween decor. And I still have no sofa in the living room and that room remains in the "meantime" stage, I almost skipped doing anything on the entry table. But I missed not having the fun of doing something to usher in the holiday. So the entry table and mantel will have be about all that is decorated this year. And a little bit outside, of course. I need to see a smiling Jack O Lantern on the porch, too.
Doesn't every pumpkin deserve a hat if it wants one? This little cone hat was fairly simple to make. It's just an embellished cone using damask paper, with a flat round bottom. To bring a touch of elegance and to the candle I, wrapped it in some damask paper, too. (Although I lit the candle for the picture, I would not leave it lit with paper on it.)
I love making Treasuries on Etsy. The one above came from a bit of insomnia last night. It happened to open at midnight. So the name is "Midnight Hour." Lots of great goodies, mostly from the Design Style Team (InteriorDesignTeam)
This treasury has ended, but you can find some beautiful things on Etsy by searching "interiordesignteam" or "cssteam"
