I’m looking into making my own spell oils and would love to hear what does the process look like for you. I’m familiar with herbs and have worked with deities for some years now.
The next step is to create potent oils for myself.
What would be your way of enchanting your oil, herbs and whether you use planetary hours / moon phases for specific workings ?
How do you charge your oils and what is the nature of your offerings you leave for your spirits you work with to make the oils potent enough 
Any other additional info you think is important in the process is much appreciated
