Christmas decorating outdoors! Provide a basket of goodies for the children to decorate a tree/shrub. Natural objects such as fir cones could be painted/embellished by the children to use as their own homemade decorations.
Make Gingerbread Play Dough! Smells delicious! Smelled yummy but was SUPER sticky, had to just about triple the amount of flour. My girls said it smelled "bad" ;) They are not fans of the smell of molasses
