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).
Since mom can't see most of the changes I've made are really to help me and anyone else who comes to visit feel more comfortable (the institutional beige everywhere was just one straw too many for me) and also to let staff know that mom has someone who cares.
We were asked to write my mom's name in all clothing. That alleviates the problem of clothing getting mixed up with other people's clothing. You can buy a black marker, specifically for making clothes, that will not wash out.
My Mom had a separate wardrobe for her clothes so I'm not sure if your Mom is in a ward for a semi-private room. If she is in a ward (multiple people), you can use her wardrobe as a display area, if you turn the back of the wardrobe toward your Mom. Then you can put pictures on the back of the wardrobe: cut-out bright magazine photos of fall, winter, summer scenes, post cards, cards or letters etc., her favorite prayers (written in large block letters), or whatever else she'd like to see.
Hope this gives you some ideas to brighten her space.
Mom was able to see and those photos brought her much happiness and it helped her remember good times throughout her life. It also was the source of conversation between her and the staff. For that reason, I think it would be a good thing for your mom to have in her room - the staff would get to know her a little better.
I had the calendars made each year at a local FedEx store. (You don't need to wait until January to make a 12 month calendar.) All I needed to do was to bring 13 pictures, and I indicated which month I wanted each picture displayed. The 13th picture was for the cover.
The calendar was reasonably priced and it always brought a smile to my mom's face (which, of course, made me smile, too).
Maybe some colorful vinyl stickers for the window or those plastic stained glass window ornaments might be nice.
When mom first moved in, my sister in law and I composed a brief biography of mom, printed it off in large type and taped it up next to the head of her bed. Several staff members told us it was quite useful to know who my mom was before her stroke.
I like the air freshener hidden in a fake plant idea, two birds with one stone. I saw a cute little fake fern at the dollar store the other day but I wasn't sure about the glass pot, maybe I can put something together with a nice unbreakable pot.
The place mat on her bedside table is a great idea too, I went right to Dollarama and picked out a cheery plastic one on my way to visit after lunch, looks good!
The folding chair for visitors is something I never would have thought of Barb, I should be able to store something in the wardrobe.
Rainmom, I like the idea of a colourful throw pillow or two, today I noticed they used mom's teddy as a pillow between her knees, the real thing would make more sense.
I do have a one nice pic of mom and dad, organizing the photos is one of those tasks I keep putting off though. Mom's favorite colour is yellow, hm, I wonder if I can do some kind of poster for over her headboard with wall decals and stickers on yellow bristol board...
We had a little plant in there and that cheered the place up but then you need to care for it. (Fake plant with coffee beans in the pot to help X out some of the nursing home smell?)
One lady at the NH had a decorated wheelchair.
The only other thing I can think of is to pick a "signature color" for your mom. My daughter only wore pink in preschool. (Her choice.) When the teachers came across something that shade, they'd always ask us first if it was hers. If her "decor" and a few of her outfits are that color, maybe they'll start associating it with her and not be as inclined to misplace her things?
My grandpa's room was always depressing. He had always liked colors and light and knick knacks, but we just never got it together. It seemed futile because unless something was out of his reach/line of sight, it got soiled. Plus it seemed inconvenient for the staff and they just pushed stuff to the corner and piled supplies on it. But I wish we had done something cuter anyway.
As far as they cloths go, I believe there are labels you can get such as https://www.etsy.com/listing/153472162/custom-clothing-labels-personalized-name?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=custom%20clothing%20labels&ref=sc_gallery_3&plkey=22d2389ed51d1afeeaa1dc7f777d740b3d55f552:153472162 that you could put her name on and just sew onto the clothes with the rest of the labels, or even on the front of her clothes like a nametag I would guess. Both of these things could be taken with you to another place if you end up moving her.
