Lowe's has a very fun site (and magazine) dedicated to Do It Yourself projects. They always have some fun ideas, and Halloween is no different. Here are some of my favorite ideas from their site.
Spooky curtains made out of cheesecloth soaked in coffee:
A candy corn bucket made from a plastic pail and electrical tape:
And the cute little ghosts made from cheese cloth and white plastic buckets.
Or these ghosts made from a tomato cage and a drop cloth:
These really fun tombstones made of foam board and stone spray paint:
And the gigantic spider web made from friction tape:
I love them ALL!
