I am able to grow calendula myself and learn to use this wonderful flower for my own cosmetic products. I love the Calendula toner and use it almost daily. The ice cubes from Calendula toner is perfect product to reduce wrinkles :). 
I made my first Calendula macerated oil from fresh flowers and grapeseed oil by cold infusion method. Unfortunately it was not success, probably too much water in flowers provoked the fermentation process.
Based on my experience I made the macerated Calendula oil from good dry flowers and sweet almond oil. The oil has to stay on sunny place to infuse for 4 weeks and I believe that this time it will be success.
For what do I need the Caledula macerated oil? To make lotion, creams, soap, body oil, to apply it to specific problem areas where might be a dry skin, inflammations, or rashes.
