You know you're dealing with the owner of the shop when the fact that you are buying a lot of items for 20p elicits a smile rather than an exasperated sigh.
So, thank you to the lovely proprietor at All Saints Pastoral Centre Bookshop in London Colney where they carry an extensive variety of bookmarks/prayer cards for 20p as well as folded greeting cards / prayer cards with beautiful illustrations by Sr. Mary Stephen CRSS for 95p. The greeting cards are really useful for notes of thanks and encouragement, so I bought six of those too!
(Sr. Mary Stephen designed the illustration that The Methodist Church of Great Britain has used for it's year of prayer, Pray Without Ceasing.)
(No, the bookshop does not give me royalties! It's just nice to be able to give credit where credit is due.)
