Mix all ingredients together and store in an airtight container (see note).
Optional: Blend in a spice grinder or using a mortar and pestle if you prefer the herbs to be a finer texture.

Notes
Be sure to choose food-grade lavender; some lavender products are for decorative purposes only.
Store in a tightly covered jar or container. Recycled containers are great, as long as they are spotlessly clean and dry. You'll need a container that holds at least ¾ cup.
Dried herbs will keep for at least 6 months stored in a cool dark place such as a pantry or cupboard. Do not store in direct sunlight or next to your stove.
