These are spiders we made about 3 years ago and we pull them out every year. We usually hang them from our chandeliers, but this year they made a great addition to our Halloween Tree.
They are super easy and can be made in very many variations.
We used a foam ball that we colored with a marker (paint would probably work better).
For the eyes we used felt, but large wiggly eye would work great too.
The legs are pipe stem cleaners just poked into the ball.
