because she's kind of snobby and also mostly blind, aside from having everything she needs, after 89 years!
Gifts I've given to my grandmother when she was blind and I was at a distance: chair massage cushion (she was mostly sedentary at that point), restaurant gift certificates (depending on her status, you could give ones that deliver), audiobooks, life story recording session.
About the latter, we had the equipment, but you needn't make it fancy. We interviewed her and recorded her telling about her own life. When it was complete, we gave her a polished up copy, and gave them out to her family.
We just did a similar prompting project for my folks; we gave them some Circa notebook supplies and asked them to write their own story. The SO's dad did it years ago at his prompting and it's been a great thing for the family to have. My dad just began his and hopes to expand it as he goes (thus the Circa, so it's reconfigurable).
Anyway, aural or tactile stuff, or stuff that smells nice or tastes good if she likes that sort of thing. We buy lots of consumables for people that have a bunch of stuff. Spend the money on quality instead and get really special foods they wouldn't normally buy.
Not that you asked for ideas! I think the flowers are awesome and should come on her birthday!
On clothing & book accumulation, I'm really on the other side of the spectrum right now. I've done a pretty good job purging in the past and I use everything I have (not having that much money helps to focus in my needs).
But now that we're in the new house that finally has some storage space, I've been thinking it's time I deliberately and carefully added to my clothes and books. I want to do it slowly, because I know I'll accumulate junk in this house and use up the space quickly and I hope to stay here for a long long time.
Still, I feel like it's about time I felt like an adult and bought specific types of clothing I want to have in my wardrobe, and specific collections of books from authors I love. I'm trying to buy hardback so they'll last (it was traumatic when my Douglas Adams' tRatEotU wore out) and I am trying to buy used (like at the library sale here where I totally scored, including a copy of the abovementioned), but I'm definitely adding stuff.
