They look great, and aren't they fun to work on?
Maybe the green, though to me I don't think it's the right colour to pull in. If it was a darker richer green, then maybe? But try it! It could be just the way the colours look on my screen.
I like the small flange idea first and then sash it up with something. It looks like some of the tiny daisies are a deep raspberry/burgundy/wine colour of sorts. I think that could really do a great job for the sashing. Something that is a nothing print, tone on tone type. Or even, it might work as the initial narrow piece.
