So you have added your scent of choice and now you need to add the melted base to the silicon donut mold. Make sure that your mold is on a leveled flat surface. If not, the soap will lean to one side in the mold, giving you a lop sided shape donut. We don’t want that as we want the donut to look as realistic as possible. Once you have added the soap base to the molds, it is time to spray it with alcohol to get rid of any air bubbles. A light mist should suffice, don’t over do it.
