We recommend students who have no floristry background to take EFA first, as it covers the fundamentals of modern European table flower arrangements through the use of flower foam and teaches 16 different design concepts with teacher demonstrations. Whereas ECO explores 12 different practical and sustainable techniques to arrange flowers in different forms of vases without the use of flower foam. ECO emphasizes foam-free vase arrangement techniques, and EFA emphasizes design concepts. We recommend students to have some experience from EFA Modern European Flower Arrangement in order to grasp the concepts better in ECO and thus be able to nurture your own creativity.
