I know there is a group of mail art folks who are into making miniature stamps. I am a massive failure at drawing or being artistic with pen and paint, but I did find these gorgeous pre fab faux stamps by K&C Company the other day. They also had beautiful adhesize papers (very large stickers!). And of course it was all on sale at 40% off. I would have bought them anyway, but it was extra nice they were on sale!
I do proudly report I took the last 2 off the self! So sorry my local PA people, but they are mine!
I hope this finds you all happily mailing!
