On Saturday my cousin and I took the kids to Durham, and wandered round the most awe-inspiring cathedral in the world, and to get damp in the drizzle down by the river. I was disappointed by the postcards available, so decided to make some studies of my own - of windows viewed from the cloister and of the Sanctuary Knocker. I hope you like the latter drawing. My son (aged 7) says it looks like it was drawn by a real artist. I took that as a compliment.
