Fill your jar about halfway with calendula petals. Pour oil into the jar until it’s just about full. Secure the lid and place in a sunny spot for about a month.
After a month has passed, pour the jar’s contents through a small strainer or a muslin bag, straining the oil (or pouring it once strained) into another clean jar or bottle.
The calendula oil infusion doesn’t need to be refrigerated—you can store it in your bathroom cabinet. But if it starts to smell a little "off," it’s probably time to toss it and make more.The oil is wonderful as a face and body moisturizer that works especially well when applied to wet skin just after cleansing.
