I think I would want to put on a border of the white about 1.5" then the floral about 2.5" and then bind in the red. But I love borders on a quilt.
At first, I thought if only a binding and no borders I'd use the floral, but now I'm thinking the red would be the thing to make the quilt pop.
So I say red for the binding. Yep, red it is.
