Feather flowers are going to be the stars of 2013. There are some amazing designs out there already that include organza or silk with Swarovski detailing and a feature vintage Marcasite or crystal brooch. Look out for the Coq feathers!
Ikebana flower designs tend to be minimalistic; the key to achieving their distinguished beauty is not in any particular single component, but rather the balance between all of them. The key is finding a harmonic balance between all the elements of expression (the container and the flowers, stalks and leaves), their characteristics (such as color, texture, form and the season they represent) and the space where the flower arrangement is expected to be used.
