These look cool, especially if the bottles or vases have water in them and food coloring to make the stick less obvious to view. Be sure the doll heads have no eyes.
Ever since I was a kid growing up on an estate that had 2 cottages, stables, and a barn, I learned to sort through paraphenalia stored away and find ways to make something new out of something old.
Halloween is a great time for this. You can use a simple wheelbarrow filled with ice to hold beer bottles and soda bottles for a party.
A 50-cent plastic pumpkin from Goodwill (or a dollar store) is great to cover a porchlight by cutting the back out so you can wrap it around, or consider using a plastic Halloween mask with eye holes.
This Jack O'Lantern head guy was some sticks I tied together and glued with twine then used air-drying clay to to make the head and painted it.
Empty water or milk jugs with glow-in-the-dark paint poured inside and stickers that show radioactive.
Spider cubes - fill just the bottom of ice cube tray and freeze, then put a spider on top of the ice and cover with water and freeze again.
Blair Witch stick symbols and corn dollies made from corn husks - those pagan-looking symbols get folks every time.
The most creepy things are found around the house. One year, I took all that Amazon cardboard and cut out wood planks and painted them to look like wood, crisscrossed them over the windows to look abandoned. Another year, I cut out a tree with a cat and painted it black, put it in the picture window with a blue light bulb in a lamp behind it.
There's something about handmade masks and decorations that looks so Old World, Pagan, Rural, and gives it a lot more spook than any mass manufactured plastic.
Enjoy - for less!
