I've done some searching, but all I can find are ideas for a private suite. Mom is in a shared ward room and her personal space consists of her bed, a side table and an ugly wardrobe. Mom can't see so my desire is to make the space more visitor friendly (I can't imagine my family's reaction to the place) and also an attempt to help staff see the difference between the rooms occupants (for example I'm finding I have to go through her clothes daily to remove items that belong to her roommates).
Definitely sounds a little dismal and a challenge to make it homey. Hopefully, you'll have your mom in the new facility soon!
I know you said your mom is blind - but perhaps a small bedside lamp? A large throw pillow for the visitor chair? Is there space on a wall to hang a couple family photos - not so much for mom but for the staff? I think it's always good to have a reminder for staff that this person wasn't always like the helpless person laying in the bed - that they had a full life and people who love them.
How about a colorful vinyl placemat for your mom's bedside table? If it doesn't fit you can cut it to size. And a table runner might brighten up the ugly wardrobe.
You can hang a tassel from the bathroom doorknob or the handles to your mom's closet.
A sun-catcher attached to a suction cup in the window?
Place a light, colorful throw on your mom's bed. Maybe your mom has a favorite throw from home?
Try to place items that are up and out of housekeeping's way.
Some of her own knick knacks placed around. Does she have a favorite clock? What about a radio? Hang something on the room divider? A small rug placed where she or others will not trip on it? A snack drawer? A bowl of fresh fruit?
