Just a black marker, some strips from and old hanky,
glue and two sizes of foam balls or beads , make :
Draw a little black mask like shape on the bigger foam ball using the marker.
Dip the fabric strips into some glue ( if needed you can thin the glue with some water) , then wrap the strips around the ball . Do not cover the mask shape. Leave to dry.
Glue two tiny foam balls or beads to the black area and draw eye balls on them. Add a tiiny piece of fabric between the eyes to suggest a wrapped nose. Do not try to work really tidy, a look that is a bit messy , is much more spooky.
There they are , you are all done. I got a bit carried away and tried the same technique on a flower pot and a basket and I think they turned out pretty well.
