I love the dog! The wreath is pretty fabulous too! It is made of tiny pumpkins which I imagine were glued on. Just add the black ribbon and you are set!
Using Christmas lights is also a big thing for Halloween. These are actually wrapped around a wire shaped pumpkin. Anything you can do to help light up the path to your entry will help those little ones out and also create a very festive feel! I love the happy pumpkins, by the way! Also, corn stalks are a big deal right now and add a lot to your fall decor without having to dig deep in your pockets. You can find these for about $3 a stalk at your local nursery!
Okay, this has to be one of my favorite ideas! This photo is from goodhousekeeping.com. I love the pumpkin "tower" placed on the black urns where I assume a topiary sat not too long ago! The black trees are just painted which you could free hand and the artist also poked holes in the pumpkin to create "stars". Just add orange and white pumpkins around and a spooky wreath and you will be the talk of the neighborhood!
And let's not forget the wreath! You can do something more festive or something like this wreath above which will take you through Thanksgiving as well! I love the magnolia leaves and the fall leaves and berries that will add a bit of color to your front door!
For those of you that want to go with more of a spooky direction, then there is only one place I suggest you going...The website http://www.hauntproject.com/ is AMAZING!!!!
