Granny square

This was the product of my efforts this afternoon at a workshop on granny squares held at Counter by Leigh Thornton. It was a fun afternoon with good company and it made me see that I have learned a bit in the classes I've been doing on Tuesday evenings - which are coming to an end this week, sadly. 

See if you can spot the (unintentional) error!

On my way home after calling in at Waitrose I met AN who was sitting outside at Caffè Nero so I stopped for a blether with him and he seemed in good form.
