A blessing jar, fostering community

I spent the day and evening visiting a close friend, and one of the things that we did was that we shared gifts as usual. They had an idea that they had made for me given my lifestyle, being a jar full of little trinkets they've gotten, with them having a sigil and a spell placed upon it specifically for the purpose of strengthening connections. They called it a blessing jar.

The idea of the jar is that I would take items from it, and share with another person to create a connection and foster friendship, and if they want to, they can share with me something they may have, and that is what got me thinking of this idea. A gathering with jars, each with items filled by the person. Maybe satchets of herbs and materials if that is you, or jars with items in them, or such, and freely exchanging in a group setting if can, else, just simply sharing what we have.

Just an idea I had.
