When making a mass-and-line composition, my usual habit is to start with the mass and then work on the lines to add a certain flow and movement. Mass is "easy" to tackle first because it is static...almost stoic and uncomplaining while a line is more hard-to-please!
Anyway, with this work, I started in reverse and formed the lines first. The beautiful dogwood branches had much to offer. The vase I had chosen turned out to be too small so I ended up using the outside of the vase. Do you see the "star" amidst the dogwood branches? That was not intended! I noticed it only while putting the branches together.
The vase, by the way, is not a traditional ikebana vase. It is actually a candleholder! I liked the shape and the clear crystal reminded me of ice (and the cold of winter!) It went well with the shiny green of the oregonia and the deep red of the carnations.
I hope you enjoy this arrangement.
