Since I had received three bouquets, I separated them into more manageable sets for my two students to paint. I was surprised there was NO whining about painting from a still life set up in front of them. (I've been in classes and workshops where there was a lot of whining about painting a still life set up of flowers.)
This is the set up Joy tried. I sent her a photo to use at home and finish (or not).
This is the set up Linda tried. She also got a photo of her own to try to finish or work on at home.
I have to give kudos to both students for being good sports, for understanding that this was a lesson in painting what you see (rather than what you think you see).
And I couldn't make them work so hard without doing it myself, so I had a set up of my own to try and paint of the white flowers. I removed the daisies from this, moved the flowers around, and painted this while it sat in front of me on the table. The trick was to get all those white flowers!!
It's not finished (need the vase to be much darker blue and to have a shadow to ground it on the table), but I'm not unhappy about the white flowers at all.
Our goal was to see it and paint it correctly without getting overly fussy.
