The techniques learned in both courses are exclusively different. If you want to learn the techniques to arrange flowers foam-free (i.e. without the use of oasis) for any size & shape of vases with any quantity of flower, then we may recommend ECO. As this course is focused on techniques, you can then apply the techniques taught in ECO to any of the floristry styles you learn from other courses. NF NUFLEUR floristry design concept is an approach to French contemporary minimalistic style. Students will be able to create refreshing and statement vase arrangements while mastering a range of freehand techniques. The techniques and design interpretations are more contemporary NUFLEUR design oriented.
