Set your oven to about 200 degrees F.
Slice the orange into thin slices and take out all of the seeds. (I kept the ends for my Homemade Orange Cleaner.)
Next, pat the oranges with a rag or paper towel to absorb some of the moisture. This will also make the drying process in the oven go quicker.
Place the oranges on a baking sheet with parchment paper.
Put your orange slices into the oven and rotate them every hour. ** see notes below
Once your orange slices look dried out you can turn off the oven and let them continue to cook in the oven with the door open.
Let the orange slices cool completely before stringing them with your twine or string.
Use your big needle to help get the twine or string into each orange.
You can string them close together or leave 1-2 inch gaps to create a more minimal look.
Once you have your string completely strung, tie the ends and knot them forming a three inch loop.
You can add cinnamon sticks, cinnamon, orange oil, or dried fruits like cranberries to enhance or prolong the smell.
You can also add things like wooden beads or greenery to give them a nice festive touch!
You can hang your dried orange garland around your tree (like I did) or simple attach it to a fireplace or another area you have Christmas decor.
