Actually, I collect 'how mail moves' envelopes from way back. I have a small envelope that was carried by pigeon, but I also have a small bit of microfilm that was also carried by pigeon! So, it just takes a small bit of microfilm, lolol!
Oh yes, the paper nest wasps. How cool! Mine build nests in various places. Their favorite seems to be an empty, metal power box. They do it every year. :-)
