I went in my yard today and picked up some small, tight pine cones. I was going to dry them out and scent them for a bowl in my entryway. I was very pleasantly surprised after 5 hours in a low oven. They had puffed up into very pretty pine cones. Bonus!
Note: When you dry your pine cones, make sure you put down some parchment paper or you will be spending a lot of time trying to get the sap off your cookie sheet.
I used White Fir, but Peppermint or Cinnamon are great during the holidays. Be creative!
