For the swirls, we used the tops of small glass jars. Get creative and see if you can find something in the kitchen with the perfect sizes - you only need to make one or two indentations per biscuit. The way to get the best pink icing circles is to use a spoon or piping bag to put the mixture on the biscuit, then carefully and lightly use the top of your (clean, unlicked) finger to spread the mixture out in small circles until you achieve the size of icing circle you want.
