Place the baking sheet in the oven and bake for 2 hours. The times will vary depending on how juicy the fruit is and how thick the slices. Check the fruit every 30 minutes and flip them over half way during the drying process.
Once they are dried and cooled, grab your paper clips and pry the middle loop away from the bottom toward the top. Then poke a hole with the smaller end of the paper clip in the dried citrus slice. That’s it! They are ready to hang.
