If asked, I'd say my 16 year old's security blanket is this
And 6 year old V's has always been green blankie
She sleeps with it faithfully every night, but it's falling apart. It upset her when I suggested we recover it, but Mr. Dork had a good idea - a quasi-pillow case for the blanket so V could unzip it and see the old quilt inside.
V chose the green and violet theme from the original blanket for her new cover.
I added some quilt batting to make the original baby blanket bigger.
Kudos to Mr. Dork.
