Fill the jar half full with the dried calendula flowers.
Pour carrier oil over the flowers to fill the jar.
Cap the jar, and make sure it is sealed tight.
Shake the jar once daily for 4-6 weeks to ensure the flowers stay covered and mold cannot form.
After 4-6 weeks, the oil will be infused with the calendula.
Open the jar and strain off the flowers using a cheesecloth or sieve.
Store your infused calendula oil in an airtight container in a cool, dark place until ready to use.
