Sounds very exciting!
I'm also thinking of 'structuring' mine my using 'paths' between flower beds and areas of 'lawn'. A tan trellis separating red and blue flowers sounds lovely, and some green leaves would only add to the contrast and give two reddish colours and two blueish colours .... One version of GFG that I've seen had triabgular blocks of three hexagons surrounding each flower block, which made attractive star-shaped blocks repeating across the quilt.
Is there an area on here to talk about one's individual projects, air ideas and ask for advice? I suppose that would be sort of like a blog post ...
