She looks better than some years ago - and how nice to see her literally un-ruffled. I'm not usually bothered by what people are wearing (not a fashionista myself) but her Sarah-Kay-doll-dresses did nothing for her. Clear lines and well-cut simplicity are so much more flattering than all those ruffles.
Why shouldn't she take up a new hobby? Many people do. We heard nothing about her lung disease lately, did we? But she may feel that she has to make the best use of her lifetime. And anyway, it's summer, and her work looks pretty, even though a bit too decorative for my taste :-)
