While surfing for things that I think are worthy to re-run, most of my favorites are super simple. I can't remember if I am re-running just my envelopes or if I am re-running mail from other people. Maybe the point of re-runs should be to find ideas that could be used with current stamps.
This was the 2016 stamp in this series. I guess you could put red peonies in place of the kumquats.
