I've had this idea for a while now and I finally did it. I think its really cool, but I'll have to wait and see what happens. I took some expired sectional and terminal area charts and cut out circles to make into mirrors and buttons. I think they're really fun. If you want some aviation themed mirrors or buttons check out my shop. I'll be listing more there and if there is a city in Washington or Oregon that you want, just ask.
Here's the first one http://www.etsy.com/view_listing.php?listing_id=6288927
