I like your items and am sure they'd carry a lot of personal value. I like the pillow case/grandma stuff a lot and as you say they are meaningful indeed, a tangible link to a person, someone who made those items. I have a few such things of my own and have some others that are meaningful to my siblings for safe keeping as well.
I can't single out a single item that is my favourite or most meaningful, they're all of great value and I treasure them.
