Trend alert: up and over
From her Dutch teacher, my 5 year old picked up the very cute habit of saying "oofta!" and I keep hearing that word, with a little bump in the middle ( OOF-ta!) when I look at these wall-and-ceiling treatments.
I think this works especially well in the first example, where there is a little ceiling angle to highlight. There is a real energy to these up-and-over stripes, isn't there?
