I’ll post this, because some of the other stuff just doesn’t count as non-aggravating 🙂 Cleaning out baby food jars and getting the glue off them IS annoying!!
Homemade gift tags/cards. I chopped some of my old cards that had just the beautiful square on the front, then cut out a matching back from the inside. Nicely enough, they say “Blessed Christmas” on the top inside, just happened to work out that I could reuse some of the print as well. Hole punch them in two spots, run ribbon through and tie with a bow. I used metallic pens to write my messages inside. And they look a million times prettier now than just the plain card.
