While I was planning and sewing this, I knew there was something not quite right. Now that it is finished and photographed, I realise I have cut the diagonal red too wide. I have rewritten my instructions and have an excuse to make another one tomorrow.
I am going to keep going until I get it right.
This is my new obsession.
One good thing is that I am collecting a large basket of small offcuts. I am going to start making a scrappy quilt top and just keep adding to it as I get more.
