You can apply Inkedibles toppers to a variety of frostings such as cookies, fresh Buttercream or Non-Dairy topping, Fondant, Marzipan, even Ice Cream. Toppers do not adhere well to a high moisture base, such as whipped creams. Hard frostings, such as Royal Icing, Fondant or Marzipan will work if you apply a thin coating of a butter-cream, piping jelly or spray a fine mist of water below the toppers. If your frosting (such as butter-cream) has formed a crust, spray with a fine mist of water before applying the toppers. DO NOT add extra moisture to non-dairy whipped toppings.
