Piping cones are indispensible when applying flowers, leaves, and frilly trims on cupcakes and cakes, and cones with particularly fine points can be used to apply henna in intricate patterns.
But you shouldn't waste your money by purchasing a huge variety of these piping cones; in many cases you can make your own for a fraction of the cost.
Watch this video to see how. Best of all, your piping cones will be of the right size and thickness.
Making cones comes in two major steps: first, get a triangle of a non-permeable material (baking paper for cooking or mylar / cellophane for henna) then actually shape it into a cone.
This video will show you how to cut out triangles from cellophane for your cones, but you can use this method for any other materials as well.
