Does anyone here know how to make Sceted Oils?

Different methods, I only know of two.
1. You take the petals of what ever it is you like, let them dry, crush them into a super fine powder, and blend it in with what ever oils you wish, olive oil, and grapeseed like or generally good for this.
2 Take the petals, or the part of the plant that is most fragrant, suxh as the fruits of fruit bearing trees, or the bark of something like a cinnamon tree, press it with (old methods were to put it in cheese cloth and twist it until the resins and or oils began to seep out.
Then, again, blend it with a base oil.

I use olive oil or avocado oil as my carrier. I just gently crush whichever flowers or grasses I want to use and cover them with oil in a clean canning jar. Have to make sure it's clean and not wet. Then I set it in the sun on my window ledge for about a week and give it a good shake every day. Then I use a hand sieve to separate the oil from whatever I'm infusing it with and put up the oil. If I want a stronger scent I leave it a few more days to seep.

Yes I Googled and found a video. WHEW! That's a lot of work. No wonder it's so expensive! But I have been wanting to do this many years. My tree only blooms after a heavy rain. And we have had a rather WET summer. Thankyou.

Go YouTube. Dozens of vids there.
