Collect seeds from flowers growing right out of your garden, and place them in a personalized, handmade packet. You can put the seeds on one side, and a note on the other with instructions. That way, every time the flowers bloom, they will think of you.
This can be great budget-friendly wedding favors, or placed inside greeting cards for the special people in your life.
