I love drying out remnant's of my teas in the kitchen's mini bay window. Cuttings and petals from the outdoors are often added to dry out. It looks like an open apothecary and smells lovely when I wash the dishes. Having a Christmas tree and access to pine put my ingredients to a holiday use. I combined an equal ratio of all dried goods in mason jars. there is no secret quantity or formula to potpourri, use what you have and scents that please you. Just boil low on the stove in a pot of water and enjoy the smell of a Christmas home.
