Floaty Toes told me about these so I went on a hunt for a free pattern and found it here @ Vegan Lunch Box - Apple Cozy Pattern. This pattern has a variation for pears at the end. That link will also lead you to banana and orange cozies. I will be gifting mine at the office holiday party this week. What's awesome about the red color is that it looks kind of like the marbling in a steak. I think I love it and will be sad to part with it, but, hey, I'm broke!
