Perfect piece!

As it has been torrential rain today, I have been getting on with an online patchwork course by Philippa Naylor. In this lesson I am trying to make perfect squares!
It has made me realise that in general I tend to approximate rather than take the time to perfect. I think I am more interested in the completion than the process.
But I have been trying really hard here, and I think this one is good!
Probably not a very interesting photo though.
