I have noticed lately my mom is rolling her clothes that she has on all the time.

As in using her hands to roll the edges of the fabric? I’ve seen elderly people do this and thought it to be a comforting, repetitive behavior. My mother used to tell me that her mother folded and refolded the same washcloths over and over, it made her happy

I wonder if she would like one of the fidget aprons (muffs, pets, blankets etc.) 🤔

This is not unusual. My Mom constantly picked at her slacks. My daughter made her a fidget muff. They also come in blankets. Moms had a zipper on it. A button with a button hole. A flap with something under it. Squiggles that could be played with, ribbons, ect.
