Melt the beeswax, shea butter, and herb-infused oil in a double boiler until melted. You can also use a heat-safe glass bowl on top of a pot if you don't have a double boiler.
Remove from heat and add the lavender essential oil, if using.
Quickly and carefully pour the mixture into a small glass jar or tins.
Cool in the refrigerator to help prevent the shea butter from turning grainy.
Use as needed after gardening or anytime your hands need some extra TLC.
Notes
Store in a cool, dry place and use as needed. I keep it in my pantry.
