Elle, I LOVE what you did with the outside border and applique..Its funny..I immediately thought..I'd do a cross-hatch (with my walking foot) on the applique border all the way around then...hmmm...let me think about the watercolor block...you definetly don't want to take away from the impact of that beauty!
Yup...went back and looked again..I'm not sure that I wouldn't do a cross hatch over the entire quilt! Whatever you choose..it will be lovely I know..can't wait to see!
