Pour half of the water in a medium glass bowl. Add gelatin and mix. Heat the remaining water in the microwave until boiling. Whisk the hot water into the gelatin mixer until all the powder dissolves.
Place the straws about ½ inch down from the top of the cookie cutter, pushing them through to the cookie sheet. Doing so will create the hole for the ribbon to hang it.
Finally, cut your ribbon to the desired length and thread it through the hole. Tie a knot in the end to secure. Allow 24 hours to air dry inside before hanging for best results.
