I believe I saw a YouTube about stabilizing fabric on freezer paper and then running it through an inkjet printer. They were ising for printing patterns and it only works for black ink but then you can use the decorative stitches to add flair.
Now for content I would have the group name, a location identifier and then year. If you want to leave a space for something about the pattern that might be interesting. I also put washing instruction s on mine "Machine wash cold, tumble dry, use often"
