Gather some flowers, herbs, and seed pods.

Spread them out on an old screen in a warm place to dry out.

In a small bowl add several drops of fragrance or essential oil to the fixative and stir well.

In a large bowl mix together the dried flower heads, petals, scented leaves, and seed pods, discarding the stems. 

Add in the fixative and any other materials you have on hand, such as whole spices or other dried materials.

Gently stir together and place in bags or jars for gifts, or simply set it out to enjoy.
