1. If your smallest son is 6 years old and wants a Monster's Party..... let him design his costume!
2. Make his costume with some poetic licence, following the plan as best as you can. Apparently spray in red hair dye is necessary!
3. Games need creating. Try including a monster target game with a big piece of cardboard and some poster paint. Fill old socks with sand to throw at the target holes.....scoring is not compulsory!
4. Take new clean paper potato sacks. Cut a face hole and two arm holes in each sack, then let the party guests draw and paint their own monster costumes. Leave to dry in the green house if rain is threatening!
5. Once dry small people can wear them and take them home as a 'party bag.'
6. And don't forget the party food. How about monster cupcakes?
