I found this idea on Betz White blog about a year ago, and fell in love immediately. Unfortunately I could not find neither the same kind of branches not the felted balls, so I had to make do with something similiar.
It's probably the easiest project there is. Get a bunch of branches, some felted balls (or small pompoms, as in my case) and glue them onto the branches.
The bright colors make me smile.
(But I do think that I might make a similiar thing with white or pale pink ones some day...)
