Here's a cheap, easy, and quick party favour to create for a child's birthday. It works particularly well for a four or five year old's party, as they're old enough (usually) to not put everything in their mouths, and really enjoy sensory play.
Buy fine sea salt at your local health food store. I got mine for less than $2 a bag containing enough salt to create two favours. Pour the salt in a bowl, and add drops of food colouring and essential oil, mixing and adding until you reach the desired intensity of colour and scent. I used lemon oil for the green salt, lavender for the pink, and peppermint for the blue.
Divide into 1 cup portions, and tie with string. Add a typed or hand printed label. Ta da! A quick, easy, cheap, and educational party favour!
When spread thinly over a cookie sheet, sensory salt makes a beautiful canvas for a small child to draw or write in. My Kindergarten students play with our salt trays on a daily basis, so I knew these "treat bags" would be a hit with my five-year-old's friends. And for less than a dollar a bag? Perfect!
