One witch might not be scary enough, how about 3 of them? This garden set up was taken from a pumpkin patch at a farm. You can do the same for your front yard Halloween decoration.
To make it easy on yourself, use store-bought witch figures; support the figures with long & sturdy sticks. Decorate the surrounding field with pumpkins, hays or heaps of Fall leaves. Instead of throwing the beautiful Autumn-color leaves in the garden trash bin, add them to your front yard decoration.
