I started off with some clean, white plastic bottles. Most of these are milk jugs from McDonalds, and the others are from orange juice, shampoo and drink mix.
I used a marker to sketch a face, then used acrylic paint to fill it in. I tied some ribbon in Halloween colors to the top of each bottle for a finishing touch.
They even look cute with a battery operated light inside...
These were super easy to make and cost very little. I love when such simple decorations turn out so cute!
