Inspired by the Postmark calendar post at The Stamp Forum boards, and more importantly, the fact that I bought a couple of Machin kiloware, I am sharing my #postmarks365 project. It’s a start and there are still many dates without stamps. While I will try to complete this with Machins only, it is very much possible that I run out of patience and add stamps of other countries too.
Update 9 Sep 2020: Here’s the progress 4 years after I started this project. As you can see, it’s no easy task finding the right 366 stamps.
