Crocheting in the dark!

This weekend I have been away on what I hope will the last expedition of the year, one of the problems of camping at this time of year is that it is dark by just after 7pm! So last night I had to finish making my square by head torch light...... Can you tell where the daylight disappeared???

Obviously with it being dark I also couldn't follow a pattern so I found myself making it up as I went along!
