The course instructor for "Elements of Floral Composition" was Jaycee Jaspar. Jaycee is a very talented Altenew Certified Educator and in this course he taught how to use Colour, Value, Line, Shape, Form, Texture and Space to design a card which looks very pleasing to the eye. I used a combination of most of these for my card design.
I was inspired by each of the 7 classes, in particular shape. I learned that using a shape behind a floral image gives the eye a focal place to land. I chose a circle shape but you could use a square, oval, even a diamond or star shape. I recently purchased the Altenew Circular Elements Die Set https://altenew.com/products/circular-elements-die-set to die cut the largest die into some navy cardstock. I adhered this directly to a A2 card panel.
