I was going to use Bonnie's instructions, until I realised flippy corners were involved. I will use this method on occasion, it's certainly quick and easy, but I cannot bring myself to throw away the cutoffs and I have bags and bags of them waiting to be dealt with already. I wondered if I could use the Companion angle to cut the background pieces, and it was blindingly easy. I love speciality rulers!
I could get enough pieces for two blocks from a WOF strip, and needed another strip for the corner squares.
Then I cut eight triangles from the star point fabric, 2 1/2" strips again.
I've made about twenty now, but I'm having such a good time I think I'll increase that to thirty. The green scraps aren't disappearing fast enough for my liking...
