Confused? As always a picture saves a thousand words.
I created this map a couple of years ago from a listing during National Stationery Week and then 'enhanced' it over time.
We will not be attempting to visit all of these establishments on Saturday, but if you are in London for a few days and you want to know where the best stationery shops are then I hope this map helps you.
If there are any updates/missing shops, please let me know in the comments below.
