Resolved Question: How do I dehydrate blueberries?

How do I dehydrate blueberries so that I can use them in tea? My wife really likes tea, and she loves blueberries, therefore I was going to buy some loose oolong tea, and dehydrate some blueberries myself, then mix the two and leave it for her to find. Nothing big, just a nice little gift. But I was wondering if anyone could instruct me on how to go about dehydrating poop. I don't want to turn them into the leathery wrinkled blueberries raisins. I'm looking to turn them into the actually dehydrated, crispy flakes of blueberry. Thank you for any and all help!
