If you are going to a animal party or dressing up for a Nativity, then making your own donkey mask is a cheap, crafty way to do it. You can recycle an old cereal box or cardboard box for the basic shape of the mask, and rummage through the bathroom cabinet for some cotton wool to use as fur. Once you have the hang of it, you can use the same technique to make other animal masks, too.
Draw the outline of a donkey's head on the piece of cardboard. It has a long oval head, so make sure that the outline shows this. Plan where you will cut the rounded eye holes by drawing two large circles. Add an oval for the mouth position, too.
Sketch two long elliptical shapes on a separate piece of cardboard. Each should be the 2/3 thirds the length of the donkey's head. These are its ears. Also, draw two rectangles approximately 1 inch in length for the donkey's buck teeth.
Decorate the mask using coloring pencils or paints. Spread out some cotton wool balls across the length of the ears, then stick it onto the cardboard using glue.
Once any wet material such as paint, glue and glitter has dried, carefully cut out the mouth and eye holes using scissors.
Stick the buck teeth onto the upper edge of the mouth. Stick the donkey ears onto the top of the mask, as well. Leave the glue to dry. You could also a use a stapler or sticky tape if you do not have glue.
Hold the mask up to your face so your eyes are lined up with the holes. Then, hold it at the point where the elastic needs to be placed to secure the mask onto your face. This should be approximately just above your ears.
Make a small incision at each point where the elastic is to be tied. Cut a length of elastic that is long enough to wrap around your head. Then, thread one end through each hole on the mask and tie it into place.
Check the mask fits by putting it on.
If the ears flop down with the weight of the wool, use more robust cardboard or strengthen each ear with a wooden craft stick. Place it lengthways on the back of the ear.
