What a fabulous idea for a new challenge - I'm in it. I love the idea of working in series (doesn't it sound ARTY) so I'm going to use this one for inspiration again.
But this time, instead of avoiding those little half square triangles, I'm going to make them. I'm going to make lots of them, and they're going to be small. Oh my goodness. At least I won't have to worry about them being wonky. My little triangles are always born with a certain ... natural liberation.
