Dont worry: she's almost dead (my mother-in-law so I'm allowed to say that). She also saves old greeting card fronts and cuts them up in a haphazard way to repurpose them as gift tags. Don't forget all the fucking flat boxes no one uses anymore but by God, they will be saved!

My mom wasn't quite that bad, but we do have heirloom cardboard boxes and tissue paper for wrapping clothing. You always knew if you saw that shape under the tree that someone was getting clothes. My sister inherited the boxes and they still make the occasional appearance at family get togethers. Meanwhile I inherited the need to flatten, fold, and store tissue paper that is still whole.

We save gift bags. Some have been passed around over a decade at this point.
