There is a technique in soap making where you use a thick wire (or a hangar, more on that in a minute) to make designs in the soap. The neatest part of soaps made using a hangar (and drop swirl pouring the batter) are the patterns that emerge when you put to soaps next to each other that were adjacent in the mold. Sometimes a butterfly emerges. Sometimes a face. And with each set of soaps, the pattern is unique and different. Here are a few soaps I have made recently and I would bet that in many cases, we all see something different.
If you make soap and want to try this out, you may think you need to buy a soapmaking tool – which you can but they are expensive and will only fit one size of mold. A much easier and cheaper alternative is to use a gear tie (you can get them on Amazon) which is a flexible cord that can be bent to fit any size old. A hangar works but is really not thick enough so if you go that route, wrap it several times in masking tape.
