To make the footprint ghosts: paint feet white & press on the paper. Use googly eyes or paint on eyes & mouth.
To make the handprint spider: paint all but the thumb on the left hand black. Press on paper. Paint all but the thumb on the right hand. Press onto paper slightly overlapping the left print. When dry, paint on mouth & eyes.
Don’t forget to date it!
Great print ideas. I love all of them. Thanks for sharing.
