Harvesting lavender

As I've cut the lavender, I place it on newspaper in a room with good ventilation. My plan is to dry it all out in a few weeks, then use the flowers and leaves to make potpourri. I'm also drying out petals and leaves from other blooming plants in my garden. Last year I made lavender wands and wreaths, which I also plan to do this year. Fresh cuttings will be used for those projects. I read an idea of making a mini Christmas tree from fresh lavender: buy a foam mini tree and fill it with the fresh lavender stems; let dry a few weeks inside a paper bag, then seal in a plastic bag to retain the scent until December.
I don't plan to make the lavender oil. It just sounds like too much work. But I did buy some in Hawaii at the lavender farm on Maui. I plan to let the plants keep multiplying and making "babies" that can be moved around the yard. They are great landscaping plants here in Utah, especially in full sun.
