While the cookies are still warm, check the holes are still there, otherwise push a straw through again. Do not remove the cookies from the baking tray until they have cooled as the boiled sweets need to harden. Once the sweets have hardened, gently lift the cookies onto a wire rack with a palette knife to finish cooling. You can decorate the cookies with piped white icing. Thread ribbons through the holes to make loops for hanging.
