Glue some curly ribbon to the front of the mask above the holes, so you can't see the elastic. If you don't have any curly ribbon, you can create your own by rolling strips of coloured paper around a pencil.

Finish off your mask by gluing on other decorations such as feathers, sequins or beads. If you are making a mask using a cat or an elephant template, can you think of different materials to use to decorate the mask? For example you could use bristles from a brush as cat's whiskers, but how will you fix them to the mask itself?
