As far as I know, all you need to do is get the herbs and scents of your choice, and mix with some oil. sweatdrop
I think your right. To make strong essential oils takes a long distilling process but just some olive oil and some crushed herbs or something should work ok, even better if you can pick the herbs and flowers fresh, after all it's the power of the plant that you are after.
If you want to annoint something with a strong scent like lavender you could always try rubbing the plant directly onto the candle or whatever. I'm quite lucky as essential oils are readily available over here from magick shops, health food stores and pharmacies.
