Why not write your mother a poem? Type it up on some pretty paper and frame it and decorate the frames. Maybe even put a family photo with it. It doesn't have to be a good poem - your mum is sure to love it anyway.
So true. She'd love it no matter what!
If mom like to read make (or buy) book plates. Ya know, those "this book belongs to..." stickers you put inside the cover. A nice cros stitched bookmark? Um, for the bath/shower you can make her a scrubby out of tulle, or you can knit a mitt out of soft cotton yarn. I like the book ideas bette. You could go with a book theme. A pair of soft slipper socks, bookmark, coupon to the bookstore, etc....
I actually really like the idea of going with a book theme... I'll have to put some more thought into that.
