If you are looking for a nice square embed for your soap, you have found it. Easy to use and clean.
When you’re ready to make soap, cut off the long embed to fit into the mold or keep the smaller embed nearby. Pour a thin layer of base soap into the mold and let it cool and harden for 10-20 minutes. Then pour another thin layer of soap, spray the embed and the soap in the mold with 99% isopropyl alcohol, and place the embed in the desired location. You may have to hold the embed in place for a few seconds. Finally, pour more base soap on top until covered.
