This would make great little hostess gift and of course stocking stuffer. I hate to waste good vodka and have made them with rubbing alcohol and it is less expensive.
GEL AIR FRESHENERS
Food coloring as desired. Dissolve the gelatin in the boiling water. Allow to cool to room temperature then add the vodka, coloring and scent. Pour into decorative jar (I use 8 ounce canning jar) with tight fitting lid, and refrigerate till set.
Later put a piece of eyelet lace (or comparable breathable fabric) on the top and screw down the ring; if giving as a gift, I would put the canning lid on, then the lace and ring.
