This rainbow brainstorming is fun on a humid day in May! We're all singing a rainbow along with you!!
I see a rainbow in pale pastels of colors, the usual rainbow order-- ROYGBIV-- arching from behind pine trees on the left down to a snowman on the right with a big pot of silver and gold stars in front of him. Maybe you could applique a representation of the building where you pay the bill behind him in the scene? Or maybe take a photo of the place, and use the photo transfer sheets to get that building in your quilt.
Then I would quilt it really wintery -- with low mares tail clouds, long swoopy tendrils of blowing wind, a few snowflakes flying, and maybe some tracks in the snow.
Please let us see what you end up doing.
Remember the Andy Williams' song? I am humming it now.
Red and yellow
and Pink and Green
Purple and orange and blue
I can sing a rainbow
Sing a rainbow
Sing a rainbow too
Listen with your eyes
Listen with your ears
And sing everything you see
I can sing a rainbow
Sing a rainbow
Sing along with me.
