Children and grownups could make their own musical instruments, masks, and cards for Mothers Day, Fathers Day, Easter or even Christmas. They could even decorate their own egg for Easter (please see Easter Activities for more information). For St George's Day they could even decorate their own Dragon's Lair.
The Art Table could be combined with some of the other activities mentioned. For example, the public could make their own hats for a show or medals for a Sports Day.
