Take a look at this ...
I recently ordered some items at ETSY from Piddix, and when Corinna mailed me the flat items, they arrived in this envelope:
I was immediately drawn to all those amazing POSTAGE STAMPS ... what I noticed within a nanosecond was that the post office failed to 'cancel' every last one of them. I will not re-use them, however, I want to re-cycle the envelope, postage and all, into the background for a collage. Won't that be fun?!
