Quilting with curved rulers to make secondary designs

I am using curved long arm rulers or templates to quilt curves and create secondary designs. My favorite curves are from thequiltedpineapple.com

I like what you did there and in the border, what design did you use in the border?

I think that is a digital cable feather named "Carolines Feather"

I really like the way you explain what you are doing. You make it look so easy.
